>>1657283Just go next level and /diy/ a CNC.
>>1657315I know it mentioned it requires a furnace that can reach steel sintering temperatures, but I can't seem to find that info again. I haven't read anything about the debinding, though, so if you could point me towards that I'd appreciate it. Besides, who said anything about home?

i need to smooth and glue together several pieces of PLA. is there some to PLA like acetone is to ABS? or am i stuck with sandpaper and two component glue?
Not sure if this is a place to ask but a few of my projects require some sort of accuracy and was wondering if anyone would recommend me a pair of electronic calipers.
>>1657341Acetone is to PLA what acetone is to ABS.
>>1657356Not him but is there a PETG equivalent that makes acetone seem like lemonade?
>>1657341I've been using weld on acrylic cement and it works great so far. get the IPS weld in 3 on Amazon for like $15
>>1657229Not really sufficient, depending on your source. I've been trying to convert some models directly from video game files to printable, and it's QUITE TRICKY. Things will print and then try to throw supports in tiny gaps that didn't seem to exist on the slicer. That kind of thing.
>>1657356Acetone IS NOT a solvent for PLA - if your PLA is being dissolved by acetone, you've got crap PLA which is either not PLA or has so much filler that that's what's being dissolved. Seriously. Stop spreading this.
>>1657375neat, thx. all i need now is find it or a similair product in germany...>>1657356tried it and it only softens the material and cases the layers to seperate.
>>1657377Check in Blender if there are separate components, try and Boolean Union them together; if not, run through Netfabb's online repair service and check it again in your slicer after it auto-fixes it.

what's the best printer for making dry sump parts? they have to be pretty strong.
>>1657455any printer with an all-metal hotend and the build volume required for your parts can do the job, but if you're printing them out of any material with significant heat resistance you'll need an enclosure, so pick one that's easily enclosed, maybe a Voron 2.1? Otherwise any old printer will do, the only company that's actually doing anything revolutionary with FDM at the moment is Markforged with their long-strand filled materials.

>>1657477>>is there some to PLA like acetone is to ABS?>sure:>Pyridine, Benzene, Ethylacetate, Tetrahydrofuran, Dichloromethane, Chloroform or Acetonitrile>have fun!Wrong. I tested benzene and chloroform and neither dissolved PLA. Chloroform slightly softened PLA after a day, benzene had no visible impact on PLA. From what I've heard THF works, but never had chance to test it.

How does /3dpg/ deal with a tight filament spool? I just noticed my extruder having a hard time feeding filament into the hot end because the filament was wrapped too tightly around the spool. Top mounted spool holder on the Ender 3 doesn't seem like a good idea when it comes to problems like this. Maybe I'll print a spool holder that sits off the the side.
>>1658032...Are you sure you don't have a tangle, anon? Can't say that's ever been a problem. What brand of filament?
>>1658032Sounds like a tangle. Cut your filament, untangle, rethread.

Bridging what looks like 30-40mm is never going to happen anyways, so the bottom of the top platform usually looks like that, I've seen much worse.The stringing test at the top can be improved with tuning extruder temperature and retraction settings.

>>1658132Depends on the test, where did you get the STL?
>>1658064>>1658068Anycubic PLA. On second thought, I don't think it's a tight filament spool. I'll check for tangles, but it looks decent to me.I'm wondering now if the problem is the spool being too heavy to rotate on the holder well enough.I just finished a 5 hr print, manually rotating the spool when it looked like it was getting too tight
hey guys newfag here. Getting an ender 3 for my birthday. What should i know before going in? anything i NEED before i put it together? like parts that improve it vastly? Any programs that are better than others. any other info for a first 3d printer?
>>1658254use cura to slice your modelsget a 235x235mm borosilicate glass plate and stick a sheet of 0.5-1.0mm thick PEI to it if you want to print PLAconsider getting a bltouchreplace the stock bowden tube couplers and tube
>>1658254I got an Ender 3 pro a month or so ago. I hope you enjoy troubleshooting. That's not to say it's a shitshow or anything, but it's a very dumb machine and you have to baby it a little, especially early on. All replacement parts are fairly cheap. You probably want to think about a replacement bed very early, I and several others in these threads have had problems with warped beds on new Ender 3s. Generally the Ender 3 is a very nice piece of tech with some weird corners cut, but all fixes are pretty cheap so as long as you're up for the occasional fix, it's a great deal. It's fun as shit though. I've been just using Cura like most people as I have no slicer preferences, and learning Fusion 360 for modeling, since evidently no one uses what I learned in high school anymore (Autodesk Inventor) and I don't even know how to get a hold of it. Order lots of filament. You'll probably need to replace the bowden tube and couplers. I've ordered replacements, but after having to take apart the hot end and fix a gap once, it's been cruising, so I'm in no rush. Just like, load up Thingiverse and start printing shit. It's so much fun.
>>1658254You're in for a treat, anon. I got mine maybe 6 months ago and I've had an absolute blast with it. Aside from what >>1658256 says, definitely look into getting some better springs for your bed. I found my stock ones were extremely weak and were easily jostled out of calibration. Definitely learn how to 3d model, if you don't already. It's something I wish I knew before I bought a printer, since I'm stuck printing other people's designs, and very poor designs of my own. You'll get a lot more use out of your printer if you know how to design your own models.
>>1658254>anything i NEED before i put it together? like parts that improve it vastly?No, keep it standard, run into problems, learn from them, then consider printing or buying upgrades based on your wants/needs.>Any programs that are better than others. Go with Cura for your first prints, consider Slic3r or Simplify if you run into specific problems that Cura can't solve.>>1658256>get a 235x235mm borosilicate glass plate and stick a sheet of 0.5-1.0mm thick PEI to it if you want to print PLARegular borosolicate glass will get good enough adhesion for PLA, no need for a PEI sheet.>consider getting a bltouchFor a first timer, hell no. Learn how manual leveling works first, then figure out for yourself if you really need to spend money on something you rarely have to do.>replace the stock bowden tube couplers and tubeThey work fine on all three I've worked with, what's the deal with this standard recommendation? If it ain't broke don't fix it (although they may be broken in some cases, just none I've seen personally).
>>1658256bro i dont speak chinese wtf? >>1658257troubleshooting is fine as long as its a learning process and not a shitty product.

I was thinking of going to college for additive manufacturing but i thought it would be smart to see if i like doing it first before pursuing it as a possible career. >>1658264thanks i dont know what most of these terms are but i know what the bed is but have no idea what these different modifications are and their purpose.

>>1658275Pro has a removable bed (which is fine) and some mild improvements like a different power supply and the fans are properly covered. As far as printing goes they are identical.
>>1658277lots of people here seem to think the bed on the ender 3 is shit. Is that something im going to have to replace?
>>1658280I think the standard bed is okay for a while, but it will eventually wear down.I got a borosilicate glass bed and hairspray, and so far it works very nice. already printed PLA and PETG without problems on it.
>>1658275>I heard the ender 3 is the best starter printer for the moneyIt arguably is.>(i eventually want to print MAYBE gun parts and everyone in those communities says ender 3)Disclaimer: be careful printing gun parts, guns are controlled explosions and when the material fails they become uncontrolled explosions. That said, Ender 3 is fine for the purpose if you know what you're doing. Or have a long enough piece string to pull the trigger.>Quick question. I saw there is an ender 3 pro, im getting that one but dont have any idea what the difference is between the other ender 3's.Minor upgrades, nothing to worry about, standard version is best bang for your buck but the fancy versions have some worthwhile upgrades.>I was thinking of going to college for additive manufacturing but i thought it would be smart to see if i like doing it first before pursuing it as a possible career.Don't. Get into general mechanical engineering first, it's much more worthwhile. Additive manufacturing cam become a tool in your toolbox for engineering, as it should be, and not your only tool as it would be in a highly specialised college course.t.

>>1658275>>1658289>thanks i dont know what most of these terms are but i know what the bed is but have no idea what these different modifications are and their purpose.Allow me to explain:>CAD programsComputer programs you use to draw stuff. This gets turned into a seperate file format, and then sent to your slicer program for, well, slicing.>Cura/Slic3r/SimplifySlicer programs. Slice a 3D object into 2D layers with a specific layer height. Said layers are then converted into machine code, which gets transferred to your printer through USB or SD.>Borosilicate glassSpecial glass that doesn't crack or shatter after heating and cooling several dozen times (heat cycles), which happens in 3D-printing. Most 3D-printed material sticks well to this stuff, making it a great material for your print bed.>Manual levelingLeveling the bed so that it's perfectly parallel to the plane that your printhead is traveling in, usually done using screws at the bottom of the bed carriage.>AutolevelingA BLTouch is one of the sensors that attach to your printhead, so the printer can perform an autoleveling routine. It calculates how un-parallel the bed is, and adjusts the Z height of the printhead accordingly. There are pros and cons to auto and manual leveling, the main pro of autoleveling is convenience.>Bowden tube (couplers)The bowden tube is the plastic tube that filament gets fed into, if you have a remote drive extruder like on the Ender. Basically, there's a stepper motor that forces the filament through the bowden tube into the print head where it gets heated, melts, and then gets deposited onto the bed. Apparently, some users here have experience iffy quality bowden tubes on their Enders, which may cause more friction and all sorts of problems. I've never had a bad bowden tube, your mileage may vary.>>1658280Try it first, if it ain't broken don't fix it.
>>1658290thanks for the help. hope to become a regular poster!
>>1658290>Try it first, if it ain't broken don't fix it.Good advice, but it's hard to tell what's broken and what isn't when you're just starting out. People are really good at getting used to broken things.
>>1658296what would be some signs that something isnt right other than the obvious of the prints coming out wrong
>>1658296True that. My glass bed is arriving today, but to get shit to print I've just been having it start with 4 bottom layers and definitely starting way too fucking close to the bed to get it to stick across warped sections.
>>1658304Read the OP for Christ's sake.>https://www.simplify3d.com/support/print-quality-troubleshooting/If prints go wrong, they usually exhibit at least one of the problems mentioned in Simplify's troubleshooting guide.Take this guy for example: >>1658305. This sounds like bad adhesion in the first few layers, as well as warping, so:>https://www.simplify3d.com/support/print-quality-troubleshooting/not-sticking-to-the-bed/>https://www.simplify3d.com/support/print-quality-troubleshooting/warping/Which gives us the following possible solutions:>Relevel build plate>Reduce first layer printing speed>Adjust temperature or cooling settings>Disable fans (for the first few layers)>Use an enclosureMy favorite solution being:>Use brims or raftsTo add to this>Having it start with 4 bottom layersAmount of bottom layers is unrelated to warpage/adhesion, you're messing with the wrong parameter here.>definitely starting way too fucking close to the bedAdjust it then, having the nozzle to close to the bed will damage either the nozzle or your new glass bed, and will result in bad adhesion.
Any newbie bed leveling advice? I own my printer for 4 days no, still can't level that bed.
>>1658317Believe me I've leveled it to death, fucked with every setting imaginable, and I print pretty much everything with a brim.
>>1658318I use a gcode that probes all 4 corners of the bed, and then the centre, and then all 4 corners of the bed. That way I can verify my bed is level throughout the bed. What are you printing on? Look for warping on the bed itself. No matter how well you level your bed, if it's warped, it's not gonna stick properly. Heat the bed and nozzle before you level. Everything will expand once it's heated up. If you're doing the paper trick, you want it lightly scratching the sheet of paper. If you have a feeler gague, try and feel for about 0.1mm between the nozzle and bed.
>>1658322I have dial gauge and I was concerned for the consistency, but it looks to not be warped.I do the paper trick, because I don't know any other way, and even if I do all the corners same feeling, prints don't turn out.
>>1658318Here's my routine:>Clean the nozzle!>Warm up the bed to operating temperature (60 degrees in most cases)>Take a 0.1mm feeler gauge (a sheet of paper will do in a pinch)>Move the nozzle to a corner of the bed, slip the feelgauge between the two, untill you can barely feel them rubbing>Repeat with other three corners (1, 2, 3, 4)>Repeat crosswise, just to be sure (1, 3, 2, 4)>Best to leave a bit more space between them, rubbing your nozzle is bad, mkay>Start print>Look if the lines are flowing into each other!A nozzle too close to the bed will print scraggly lines or a very thin layer you can look through. A nozzle to far from the bed will cause lines that don't flow into each other, resulting in spaghetti once you take them off. I prefer starting off too far, and then adjusting untill I see that perfect line flow - on my uni's UM2's I would regularly skip the build-in leveling wizard, and just adjust by hand while the printer was working on the brim, restarting once if necessary. The look on a teacher's face once he saw what I was doing was priceless, ''But you should always use the leveling wizard!''.>>1658321>If it ain't broken, don't fix itSounds like you kept fixing it untill it broke, meaning you need to go back to square one. Clean the plate with isopropyl alcohol, grab one of the prints that stuck on the old buildplate (you do archive all your prints, right?) so your new ''improved'' settings don't ruin your print. if the above leveling trick doesn't work, level the bed way too high (1mm), start that old print and then keep adjusting the bed higher and higher untill it does stick. Assuming your temperatures/speeds/cooling is fine, this should work (but you should post them regardless, maybe something is wrong). Sorry if I come across a bit harsh.
Just got a printer and had it miscalibrated on Z leaving some very visible marks on the printing surface before I could stop it, is it fucked? I'd say they're probably 0.5mm deep.Should I get a glass plate instead?
>>1658336>Just got a printer and had it miscalibrated on Z leaving some very visible marks on the printing surface before I could stop it, is it fucked?I am currently printing on a cratered Ultrabase on my Chiron, prints just fine. They even sent me a replacement under warranty, it's been sitting here for several weeks because printer is fine comrade.>I'd say they're probably 0.5mm deep.Everybody says they've got a 20cm penis, but I never trust measurements taken by eyeball - use some calipers.>Should I get a glass plate instead?Have you tried printing with the scratches? If it sticks and the bottom looks acceptable to you, why bother?
>>1658343I printed a small test object and it got loose after about 2 hours, but could be other reasons. I'll play around with it some more and see how it goes, thanks.
>>1658335I watched all the videos on troubleshooting adhesion problems and tried pretty much everything. Always results the same, sticks fine in all but the center bottom right area of my bed, which is warped. So I'm replacing it. End of story.Besides, I'd like that nice smooth bottom action.
>>1658254Prusaslicer and Sn4k3's profiles will be a big help. I literally just got mine last week and I have yet to experience any probrems. For bed leveling check out CHEP bed level gcode.
What's the best way to dry PLA? Can I just set the oven at some temp and then set the spool in?
>>1658377Yes. As long as your oven is accurate and doesn't overtemp at such low temps.
>>1658377Do you want to get cancer? Because this is how you get cancer. Best way to dry PLA is in a chemical drying over, set to 40-50 degrees for 24 hours. Once your filament is dry, keep it dry by keeping it in an airtight container together with your silicone bag collection.
>>1658384>Do you want to get cancer? Because this is how you get cancer.Yes, listening to this Anon definitely causes cancer.PLA is not toxic. So long as the filament really is just PLA without anything like styrene snuck in, baking it in an oven is fine. The reel itself is probably just PP and cardboard.
>>1658384>heating up PLA, one of the most harmless plastics, at 50C, way under the temp of anything really happening to the plastic, other than air evaporating a bit, will give you cancerthanks anon, great post!
>>1658404If it doesn't give me cancer will it give me holes in my brain? Even more holes I mean.
>>1658406maybe if you jam a length of filament in there
>>1658254Use a set square while assembling, make sure everything is squared up, one of my upright extrusions was leaning back a bit and caused all sorts of bed levelling issues, even with a bl touch.
My friend just gave me three of these boards, I can't find any info on what they are model wise other than that I know they are for driving the stepper motors. Any idea on what the name/model/manufacturer of this board is specifically? Any piece of info to help Google would be appreciated.
>>1658472it's a random Chinese stepper driver/controller. Driver chips are easy enough to look up, but god only knows what firmware is on that microcontroller.
>>1658485presumably its some kind of serial, connect to pc and ask it who it is.
>>1658257>no one uses what I learned in high school anymore (Autodesk Inventor)My entire office uses it, and we work with aerospace stuff, so it's not completely dead. Lots of the third party models we have are from Solidworks though
>>1658353>Slap on the glass bed and level>Instantly perfect bottom layerFucking fantastic. Now I just wish there was a better option than these stupid chip clips to keep it down. Anyone have a preferred solution?
>>1658658Most people seem k with the clips. Quick to release and everything. My bed came with an adhesive bottom. Really not sure why, it does literally nothing as soon as you turn on the heat.

The elegoo mars was mentioned a thread or so back, i got one in the sale, but haven't seen anyone else post about it, pretty good experience so far, took me about 10 minutes to set up and be printing the test print (custom rook)they came out great so i tried a model with supports, using the chitubox default settings/supports i had a couple print failures where it stuck to the fep as the default auto supports in chitubox aren't so great, after more tests with manual placement and different settings i have a better way which requires minimal manual support placementmy method now is to open the stl in prusaslicer, fix, rotate and add supports, export the new stl with supports, open that in chitubox, then slice it with the 'rook' settings (the default chitubox settings are different), not had any failures since i started using this method, I have also updated to the epax firmware which enables network printing and turns the fan off unless its printingpic is most recent print, a necron cairn ship for battlefleet gothic ~8cm diameter, elegoo transparent green resin, thanks for reading my blogpost
what printer <$300 is best for only doing functional prints? or is that entirely based on material
>>1658727How is the smell/mess situation? Have you tried to slice and print directly from prusaslicer?>>1658732For functional prints you need an FDM printer, so most likely Ender 3
>>1658658if you don't want to use clips you can get a silicone thermal transfer pad and just lay the plate on top of it.
>>1658741there is a smell, doesn't really bother me and it's not too bad with the cover on, the ipa for cleaning is a lot more harsh smelling, apparently the elegoo resin doesn't smell as strong as anycubics, but i've not tried that,mess wise i let the model drip for a while after its finished so most of the liquid resin goes back into the vat, there is a part you can print to hold the plate at an angle for dripping, i haven't bothered, then i take the platform off, scrape the print off onto a sheet of paper towel (set the support raft angle in prusaslicer to 45 to allow the spatula to pry underneath, default is 90), you can see the green line on the towel from the edge of the platform which is the most mess, then fit the platform back and put the cover on, for cleaning i dunk the model in a pot of ipa swish it about for 5 minutes, i clip the supports before curing while they're still a little flexible so i don't get shards everywhere, then i put the towel, supports and gloves in a waste box which goes outside to cure, then into the bin,prusaslicer outputs a different format (.sl1) to what the mars uses (.cbddlp) i don't know if you can convert between them, not looked into it
>>1658745.sl1 is literally a zip file with an image for each layer and a little document that contains the settings.
>>1658658buy swiss clips, they dont stick up as much.
>>1658747i've not looked into it, but a quick search throws up a tool for converting from .sl1 to photon (i think they're the same as .cbddlp) which seems to rotate the images by 180 and change the format of the settings, so doable, but not sure if there is any benefit to doing it that way
Is the crealty cr 10 really much of a step up from the ender 3?
>>1658280I threw on a 5mm glass sheet on the bed and that fixed the warping. The stock magnetic bed is quite shit on it tho. It works on smaller prints and you can always choose to print on the straightest corner.
>>1658807No, it just has a bigger build volume.
>>1658807In terms of print quality and features? No, if anything the added bed mass will result in more ghosting just by design.However, if you want a cheap 300^3 mm printer, the CR-10 is currently the best value you can get. For the 400^3mm range it's a tossup between the CR-10S4 and the Chiron, the 500^3 mm market is dominated by the CR-10S5. Just figure out beforehand what size object you want to print, choose your printer accordingly and remember that smart splitting of prints is always the best option.
>>1658828>>1658816Thanks Im mainly looking to print minis and terrain for my dnd games. Maybe some castle walls and towers etc.
>>1658861Tomb of 3d printed horrors youtube channel will be your shit.
Anybody try this? Or anything like this?https://www.thingiverse.com/thing:2047554Looking to upgrade my spool holder since I noticed my current spool needing a bit more than a light tug to get it moving.
>>1658861>MinisBetter off with an SLA printer, unless you tweak the hell out of a solid FDM printer. Can be done on a CR-10 mind you, just don't expect 0.2mm resolution in your minis.>TerrainCR-10 would be perfect for that, depending on the terrain blocks you plan to print.
>>1658872Stock spool holder on the Chiron is shite, printed that one, it fell off the table, stuck it on with double sided tape, never had any problems since.
>>1658872Yes, greatly prefer it over center-mount holders.Only downside-- you have to use spools with smooth rims. That's most of them these days but not all.
>>1658873>Better off with an SLA printer, unless you tweak the hell out of a solid FDM printer.Not really true. Just go to a .25 nozzle. It's all the tweaking needed, at least on a decent printer like a Lulzbot or Prusa.
>>1658874>>1658875Fantastic. All my spools are smooth rimmed, and I have some spare rubber feet kicking about. Thanks anons.
>>1658097dude this looks great. just adjust retraction speed higher and retraction distance, go cooler on temp if you can
>>1658727wow, thats a nice print
Does anyone have recommendations for printing with TPE, TPU, TPC?I own a standard (un-modded) Anycubic i3 Mega.Do I need a special extruder?thanks
>>1659216You need a direct-drive extruder, bowden won't work well. Ideally a Titan Aero.
>>1659221are these hot ends / extruders generally cross-compatible or should I spend a few hours researching hot ends / extruders that fit my machine (Anyc. i3 Mega)?
>>1659234You won't be able to mount a different extruder just like that, you'll first need to look for an x-carriage design that allows you to mount your specific extruder of choice and then print it. For the titan aero a quick search gives this - https://www.thingiverse.com/thing:3042297 ...but the aero is expensive, so if you want to use a different hotend/extruder combination you'll need to see if someone has designed a mount specific to that. Or design one yourself if it doesn't exist.
>>1659221Need is a strong word anon.
Screwing around with a DRO mount for my router table.
Why would I have striped extrusion like this?
>>1659369Try 5 degrees hotter. Nozzle likely too close. Check to make sure you're feeding well.
>>1659369Nozzle is too close to the bed
>>1659433Yes if faggot

What videos do you guys recommend for learning Fusion360? I tried a couple tutorials but had trouble modelling a fucking jar lid.
>>1659663just go at it desuno need for tutorialsgo into the sketch mode, draw a shape using the circle tool and the line tool and then press E to extrude that shapeyou can pick up the rest of the features as you go, for now just sketch on a given plane and then extrudeit's really simple
>>1657360>>1657353>>1657451Get the 15 dollar harbor freight ones... You're 3d printing not making aerospace components... Why buy calipers that can cost almost as much as his printer?
>>1659709>You're 3d printing not making aerospace componentsThere's no reason those can't be one and the same, there's nothing inherently wrong with printing quality parts>>1657353I can vouch for the Mitutoyos as well; probably anything off of McMaster-Carr is decent
>>1659713No just no reason to spend ~$100 on calipers for his sub $200 ender 3... But you're right he should go pick up some carbide tipped mit 0-12s cause you know he's not a poorfag he can afford it, what's $800 to a college kid on a budget? The $15 dollar harbor freights zero out and repeat dimensions and can go back and forth between inch and mm I'll take the 85 bucks I saved and buy more firmament. tots a poorfag tho pic related
>>1659727You're acting like the calipers will ONLY be used for his 3D printer (which, they didn't even directly mention, as they said "few projects"). Do you buy a new nozzle for every print? New plate for every type of meal you eat?>carbide tipped>college kid on a budget>$800 calipersWay to pull words straight out of your ass.Good tools last long.
>>1659732My bad theyre only 500 on sale but my point still stands, mitutoyo anything is overkill for 90% of 3d printing, especially if he's coming to fucking 4chan for advice, but if he's not a poorfag of course he can afford them so he can totally show me up on a Chinese manufacturing forum. But you my friend need to get your sarcasm filter fixed
>>1659751I don't know what you're trying to achieve with your cherrypicking but this is on the first page of results on Amazon Prime for "Mitutoyo calipers". There's no way you arbitrarily happened to pick an expensive 12" caliper when the majority is 0-6" or 0-8".
>>1659762why go for mitutuyo? Your tool is going to be more accurate than your machine.
>>1659763Why not? Who says the calipers would only be used for 3D printing? Surely you can think of more things to measure than just parts or the printer? I have no idea why you've taken such offense to the idea of getting a decent quality tool
>>1659764I'm not him, I just typed that question. Also i'm mechanical engineer and can't think of any use for good quality calipers outside of work, they cost shit ton to maintain and are way too accurate to be useful for anything I do.
>>1659766>can't think of any use for good quality calipers outside of workI guess you don't do home projects? I use mine several times a week.>cost shit ton to maintainI don't understand. I've never had to "maintain" calipers and they've always kept their accuracy. The only thing I can think of is dirt getting into the rack/gears, and I don't use calipers where it's dirty
>>1659768>I use mine several times a week.I use mine also several times a week, but mine aren't that accurate, they are cheap 30bux once, because accuracy isn't critical in my home projects, if you need that accurary sure, more power to you but if you buy expensive tools because you perceive them better, you are doing something wrong.>I've never had to "maintain" calipers and they've always kept their accuracyHave you tested them for consistency?most calipers even if they are kept in good storage will loose their calibration doe to expansion and contraction due to heat in two years.
>>1659763>>1659766This guy gets it My point is that if he buys the cheapest mit digimatics then he's 2/3 to all the way to buying his second printer for a printer farm I specified digital because they go back and forth between inch and metric quickly and easily and can be used to do quite alot of specialty measuring without doing math Now the harbor freight digital calipers will perform 90% of the mits at one tenth the price at an accuracy more than adequate for 3d printing or home use, idk about you but I rarely need sub .005 dimensions around the house and 90% of my home needs a satisfied by a fucking tape measurer. But since as was mentioned earlier since the original anon isn't a poorfag (unlike most hobbist 3d printers who are in fact poorfags or college kids and would probably rather buy a second printer or more filament than hundred dollar calipers) wel he can most assuredly afford the best tool available to him so fuck yea let's get those 12 inch carbide tipped digimatics, money is of course no object to him.
>>1659751>>1659762Allow me to interject, but i use vernier calipers and i'm fine. If you absolutely need to measure things that are smaller than 0.05mm just get a micrometer.
>>1659709Cheapo electronic calipers crap out much faster than brand name stuff like Mitutoyo, meaning they always run out of juice exactly when you need them. They also lose accuracy as their voltage supply drops, and that can get into the range of the accuracy of a 3D-printer. If you want accurate and cheap, get name brand vernier calipers. If you want accurate and easy to read, get name brand digital calipers. There's no need to save a small amount on cheapo measurement equipment when the proper stuff will last you a lifetime.
>>1659763>Your tool is going to be more accurate than your machine.If you understand anything about measurement, statistics, Gage R&R and such, you should know that it's a good thing to have measurement equipment that is an order of significance more accurate than the deviation of your products.>>1659771>I specified digital because they go back and forth between inch and metric quickly and easilyThis isn't necessary per se, if you're in Europe you hardly need to work in imperial. Even if I need to, using metric modeling still works unless you need a precision fit (in which case you need a micrometer, not calipers), or a specific thread pitch (in which case you use thread gauges). I'm doing fine with a set of TESA dial calipers that cost me 25 euros, they're easier to read than verniers, don't run out of battery like digitals, and most importantly: don't get ''borrowed'' because everybody here uses Mitutoyo verniers.
>>1659772I'm sorry to tell you, but most people here can't read vernier calipers.
Friendly reminder to NOT upgrade cura to 4.2.1
>>1659855thisalso every update after 4.0.0 fucked slicing for me, models were stuck halfway into the build plate
>>1659856The fags just went and changed the default profiles for all the creality printers, copying them from the creawesome fork because "hurr everyone was using them so they must be better"Except when you save a custom profile in cura it only saves your edited settings, so all the settings people left to default got overwritten (including fucking line width that got changed from 0.4 to 0.44)
>>1659813>If you understand anything about measurementin metrology there is this thing called "accuracy" that is defined as "accuracy of output to true value" if output of your measure is too fine, you are wasting money. if your output is too rough, you aren't wasting enough money.
Holy shit. I did not realize you bastards would make such a fuss over my caliper question. I flipped a coin and will save for the weeb caliper since I will need it for other projects as well. The 3D prints are for rough prototypes.
>>1659872Get the weeb vernier calipers if you want to save money, or look for used digital ones.
>>1659872You could get cheaper calipers, like Bahco or Neiko, Mitutoyo is not only game in town.
>>1659813Mitutoyo calipers are only accurate to .001", so you'd better bust out another thousand for a micrometer set.Getting super accurate is much less important in 3d printing than machining. If you need perfect fit on something, you can always just print multiple mock-ups in different sizes to check a single portion of a build before committing to a multi-day complex print. Try that on a huge steel part with multiple milling operations.
>>1659883>Mitutoyo calipers are only accurate to .001", so you'd better bust out another thousand for a micrometer set.0.05mm actually, so about 2 thou.>you'd better bust out another thousand for a micrometer set.Like I literally said, you only need micrometers if you need precision fits. The average 3D-printer guy will not get below 0.1mm (4 thou) accuracy, and that's way too big for precision fitting, so no micrometers needed.
>>1659860for 0.4 nozzle a line width of 0.44 is prolly better than 0.4
>>1659883>>1659885My bad, the digital ones are indeed 1 thou. The vernier ones are 2 thou.
>>1659874I'll look into that further. Thank you.
>>1659855I can't get the damn thing to print proper supports. It's leaving some ridiculous overhangs even when I turn the angle setting all the way to 0.
>order ender 3>not even here yet>already ordered $150 in mods this is gonna fucking kill me
>>1659901There are lots of issues open on the github about supports. They really messed up this update
>>1659909refund that shit dudeit ain't worth ityou could have bought a used prusa or something for that price

Alright fellas, I suck at design so some advice would be helpful here.I want to print an enclosure type thing but my printer is too small to handle the size I want so I've split the body into four corner brackets that need to be joined at the points highlighted in pic.Interior looks don't matter and strength isn't really a concern either since it'll be reinforced by the top and bottom panels.How would you design those corners so that I can affix them together in a way where from the exterior they look as flush as possible?I was thinking of using snap joints but I've never designed any before + too much tolerance and they won't be as snug as I want.
>>1659855>upgrading past 3.6That UI man, I just can't deal.It's like they thought they were designing a slicer for phones.
>>1660070>print an enclosureThere's a reason why nobody prints them - it takes a long time, it looks kind of bad, and there's much easier ways to put 5 walls around your printer (usually acrylic). It might also deform over time if you're making a heated enclosure.Try a dovetail joint or look into other methods of wood joinery and apply those to your design, I've found they work pretty well with printed parts since you can design the exact sizes you need and not have to rely on an existing cutting tool.
>>1660076I think he means an electronics enclosure, not a printer enclosure, cumbrain.
>>1660076>>1660084Bingo.I appreciate the thought though, a dovetail might work.
>>1660084No need to be an asshole about it
>>1660090>No need to be an asshole about ithow new
>>1660090>No need to be an asshole about itno need to go all reddit about it
>>1660090>No need to be an asshole about ityour first day here?
>hotend fan isn't working>can still stay steady at 200c do i need one?
>>1660194Eventually heat creep will get to the filament and/or drive gear and probably give you feeding issues, so unless you've got a really good heatbreak and heatsink, yes
>>1659813Hate to break it to you buddy but you know you're on an American website populated by Americans? The only metric most people not into 3d printing know is 1,2or3 liter soda bottle sizes. The ability to switch between inch and mm at a button press is invaluable >>1659808Yes cheapo calipers eat batteries faster than higher quality but 3pack of button cells is what, 5 bucks at Walmart? As far as the accuracy loss the damn things won't even power on before they loose so much accuracy that they won't be fit for use 3d printing
>>1660227Genuinely curious. Is there any benefit over metric that US customary uses other than local familiarity? I only ask because I briefly heard this suggested in passing.
>>1660247it makes division by certain bases easier.
>>1660247The first thing that immediately came to mind is drill sizes. Fuck whoever came up with this stupid sizing system.I just read your post again and realize this wasn't what you were asking, but fuck this thing anyway.
Can anyone recommend a cheap entry level printer that I can buy of something like Aliexpress?
>>1660274ender 3, get it from the creality3D store
>>1660278I see those are on Ali, is there a reason for going through their store specifically? Probably to avoid counterfeits I imagine.
>>1660247There is no practical one... What's easier to figure between a 9/16 socket and a 5/8s or 12mm-13mm obviously the metric is easier... But we're back to back world war and moon landing champions so inch is obviously better /sarcasm. It's just what we were taught in school so it's what we use
>>1660227>Hate to break it to you buddy but you know you're on an American website populated by Americans?And therefore I know both metric and imperial, thank you very much. Americans should do the same, really, both systems are equally useful.>The ability to switch between inch and mm at a button press is invaluableNot really. You can draw metric parts in imperial units, and the end result will be close enough in FDM 3D-printing.>>1660227The problem isn't that batteries are expensive, the problem is that they run out when you need them (time = money).>As far as the accuracy loss the damn things won't even power on before they loose so much accuracy that they won't be fit for use 3d printingThe worst part of cheap calipers isn't that they die - it's that they give false readings when they're dying.https://www.youtube.com/watch?v=KnDype-j3hk

>>1660591There isn't much to buy in the 500 USD and lower segment that isn't chinkshit, so you might as well buy the most popular one with the most support and a reasonably good (but not exactly perfect) track record.

Does anyone here know of any premade tool changer solutions you can buy (brackets, servo mounts etc.) that don't cost an arm and a leg like E3D's experimental rigs? Or ideally a design you could print that's known to actually work.
>>1660601>Or ideally a design you could print that's known to actually work.>known to actually work.this makes it sound like you want a toolchanging system that's "plug and play". Those don't exist, they all have to be tuned around your specific setup and hardware.
>>1660595okay, suppose that makes sense. i want to dip into trying this stuff and i dont want to sink a shitload into it, and i dont really plan for my builds to be very large at all. i plan to use other materials in my projects and print the more finicky smaller parts
>>1660603Not "plug and play" exactly, i meant something that's known to work reliably with good repeatability. I'm still on the fence on whether to go with IDEX or a tool changing setup for my printer. IDEX looks more reliable, but tool changers don't require an extra stepper and driver and can potentially have more tools.
>>1660610those aren't the only options. you could just get an e3d Kraken like a normal person.
Is there a STL trove for miniatures and terrian to print that is not already on Thingverse? Looking for Printable Scenery especially.
>>1660611Not a big fan of the multi-head hotends, they're widely known for having the idle nozzle ooze and leave boogers everywhere on the print.
>>1660630then get a cyclops and waste half your filament on purge blocks.
>>1660633IDEX is better than that though - at the cost of an extra stepper and driver you get no purge blocks, you can mix direct with bowden, have different temps per material, you can do two copies at the same time... Believe me, i've weighed all the options and i've stopped on either that or a tool changer.
>>1657190Ok so I see the suggested options for a first timer buying a new printer, what should someone who is rather shit at building and debugging get for the less than $600 range?
>>1660666no matter what you get, you'll have to "debug" it, it's part of the process. The good news is that it's fairly easy and once you learn it, you've got it. It's not that hard.Prusa i3 mk2s kit is $600.
>>1660597Prusa's just onions shit. Literally the only advantage of buying a Prusa over a totally opensource chink machine is if you're low IQ and need constant customer support.
>>1660722>Prusa's just onions shit. Literally the only advantage of buying a Prusa over a totally opensource chink machine is if you're low IQ and need constant customer support.Mmmmm, no. It's an old troll, and it's getting tiresome.
>>1660591>recommending a bowden style printer for anyone ever
>>1660732how often do you print very soft flexibles
I got my ender 3 just a few weeks ago and I have yet to have a single fucking problem. I had one (1) failed print that was due my own failure. I am on my third roll of fillament and it is the tits. Prusa is cool though but I am happy I was impatient and decided to go a cheaper route. Maybe I was lucky but I suspect a small few you are literal brainlets.
>>1660734Never with a bowdennnnwhat the hellllfuck it's oozing againnnnn
>>1660722>Literally the only advantage of buying a Prusa over a totally opensource chink machine is if you're low IQ and need constant customer support.That's why all the chinese printer buyers spend all their time replacing parts to bring things up closer to Prusa's standard?Prusa is the only minimal printer that uses high quality parts across the board, as opposed to whatever was cheapest out of some Shenzen basement that week. And is also open source.Not to say it's perfect. But it starts way the fuck closer. I want to mess with my printer out of the box, not spend months trying to get it passibly working.
>>1660732>>1660734so im guessing bowdens a problem with flexible soft stuff. is this something that a new person operating in a budget would do ever for any reason, and not of upgraded by this point? is this likely to become an issue for me or anyone starting with an ender, ever?
>>1660739flexible filaments have very few uses because they're not actually soft. they're like tire rubber. they're very durable and have insane inter-layer adhesion but practically, there's not a whole lot of instances in which you'd actually want to print it.bowden machines are fine.
>>1660739>so im guessing bowdens a problem with flexible soft stuff.Yes. Not all flex, but it gets harder as the flex gets softer.>is this something that a new person operating in a budget would do ever for any reasonWell, yeah. If you don't care though, you don't care.>and not of upgraded by this point?Going to direct extrusion on a chink printer is gonna be annoying and cost as much as the printer. or more. >is this likely to become an issue for me or anyone starting with an ender, ever?Only if you care about flex filament.It's a limitation of bowdens. All bowdens. Not just cheap chinese printers.
>>1660740>flexible filaments have very few uses because they're not actually soft. they're like tire rubberDepends. Some are very soft.I use them to make print-in-place flex hinges for mechanisms.
>>1660744>I use them to make print-in-place flex hinges for mechanisms.you could do that with PC or Nylon and not have to worry about multiple extrusion.
>>1660746multiple extrusion isn't a worry. At least, I have no trouble with it.Neither PC nor nylon deal with long term fatigue very well. And both warp.
>>1660749>Neither PC nor nylon deal with long term fatigue very well.??? PC is THE material used for living hinges in the injection molding industry
>>1660751Pure PC? I disbelieve. The stuff crazes like nobody's business under static deformation load.
>>1660752whoops i was thinking of PP, my bad
>>1660753Oh, there you go. Yeah, that sounds more like it.
>>1660753>whoops i was thinking of PPYes. Yes you were.
I've been trying to print with Gizmo Dorks PC and any large print fails about halfway through. I have a heated build chamber at 55C and am printing at 275C with a 120C bed. It seems I can only ever print small objects with this. I am printing at 20mm/sAnybody have experience printing with these kinds of materials have any tips? My prints are just coming apart mid print, It seems like they might be warping apart but I can't tell for sure since it always happens over night. I've had good success with hatchbox PC but they stopped selling it on amazon and elsewhere the price went up from 30 to 50 bucks.
>>1660762add a lizard heater bulb to your enclosure so it gets hotter
>>1660765I already have 2>>1657790the print in that image cracked an hour later before it was finished.
>>1660767gotta cool the stuff super-slowly. Like bring it down to room temp over an entire day (depending on item size). Heat doesn't conduct out of the inside very quickly, PC is a good insulator.
>>1660586>no one who posts on a Mongolian throat singing forum is getting up to those temperaturesWell... don't be so sure about that. I know at least one other person in this thread does high temperatures. They do Ultem and I think are trying to do PEKK; I've done PEKK, Ultem, PVDF, and will be trying PEEK soon. Amateurs and people new to printing aren't the only regulars here.
>>1660671>>1660682Prusa no longer sells the MK2S (on their site, maybe you can find new old stock or secondhand), but the MK3S is great. $800 (flat, delivered to your door, no extra costs), though.
>>1660762Are you sure there's no hidden drafts somewhere, maybe through cracks in the enclosure? It might be a heated chamber, but there's still the chance of a small amount of cold air coming in through a seam and screwing things up.
>>1660722why the fuck do you keep going on and on about prusa not being open source when that is blatantly not true?
>>1660739>>1660734even with nonflexibles bowden are fucking shitgoing from a bowden to a direct drive made a world of difference to me

>>1659216Print very slow.
>>1660739do NOT use direct drives, it makes the extruder block very heavy and it overshoots when changing speeds during print so you end up with ugly poops all over the print

>>1660605Consider that SLA printers are also getting cheaper, and if you're only printing extremely finicky parts they might be a better option than FDM.
>>1660732>>1660736I have printed flexible materials on bowden printers just fine. For 95% of all users they're fine, which is why they can be recommended for first time users.>>1660817>going from a bowden to a direct drive made a world of difference to meWierd, it made zero difference for me on an Anet A8 (was converted to bowden by someone else, I took it back it direct drive), and I printed flexible materials just fine on an Ender 3, AC Chiron and UM2 (so across the quality spectrum).
>>1660851>Yet another feeble attempt to trash-talk Prusa printersThe only worthwhile argument i ever see out of these posts is that the printers are expensive. Any other gripe about open-sourcedness, quality control, usability or support always falls flat on its face. There has even been this funny *seething* pasta people whip out whenever a Prusa vs. Chinks debate comes up. Prusa has remained the most open-source friendly company i know, their fork of Slic3r is a joy to use and freely available for someone like me who has never bought any of their products. Yes they're expensive, but that pretty much the only option you have when you're not based in Shenzhen. Like >>1660860 said nobody can beat the chinese in the race to the bottom, so why not make something that works well and is at least more affordable than an Ultimaker.
>>1660919Uesh but the prusa mk3 kit starts at $745. Not really affordable.
>>1660969that's what the good parts cost. As for 'affordable' it depends-- I just bought two more for testing during parts development.
>>1660969You can download all the parts, print them, and buy off the shelf bits for everything except the control boards. And I think the Chinese have cloned that, god knows if it'll run compatible firmware.Even with crap parts, I wonder how much you'll spend on it...

>>1660738>Not to say it's perfect. But it starts way the fuck closer. I want to mess with my printer out of the box, not spend months trying to get it passibly working.Yes, I know you're a brainlet and it would take months for you to have your printer working. That is my entire point. Thank you for supporting it, Prusa NPC.
>>1660919Yes anon. The argument is the Prusa is overpriced. Good job finally understanding it. Boy, Prusa users sure are getting smarter by the day!
>>1661075>Yes, I know you're a brainlet and it would take months for you to have your printer working.That's really all you've got? That you're somehow 'smarter' for buying a printer that needs upgrades out of the box and constant attention to do reliable prints?
>>1661084Oy vey! Did you post from your iPhone or Mac?
>>1661087projecting hard dude.
>>1661038>acrylic is opaque to medium IR anyway.Acrylic is IR transmissive, that's why it's used for the little windows on remote controls. Foil, on the other hand, reflects like 93%.
>>1661115>Acrylic is IR transmissive, that's why it's used for the little windows on remote controls."Wrong IR" Remotes are near-IR just barely past red. Heat is a much much longer wavelength.
>>1661091>Prusa AND a thinkpadWalking meme
>>1661150both worked out of the box, dude. Nor has either stopped working at any point :-)
>>1661151I'm sure you're very proud of being so low IQ you can't easily upgrade them yourself... ;)

>>1659663>I tried a couple tutorials but had trouble modelling a fucking jar lid.
>>1661268to be fair, threads are hard unless you use a pre-scripted/modeled cheat.
giving polycarbonate another shot
>>1661278prolly work better on the inside, on the outside it has to go back through the acrylic and you probably lose some energy that way
>>1661280I figured as much but thats to much effort. It is already about 5C hotter than normal and it just started so it is working some. I think printing at 10mm/s will be the best chance at success.
>>1661278are you using 100% polycarbonate or some mix like the ultimaker pc?
>>1661278Nice setup. Is this a cr10? Do I have to upgrade something to go >300C besides a full metal hotend on a creality machine?
>>1661269>to be fair, threads are hardNot really. Difficulty depends on how you want to add them and how accurate you want them to be. For machining purposes the threads in the model aren't important for anything other than visual indication because the spec notes will be followed instead.In Solidworks and Fusion you just make a bore in the minor diameter, then pick an edge to Tap the thread from, and choose the diameter, pitch, and offsets. For male you make a bore with the major OD of the thread and pick the parameters. Then add a thread relief as a revolve cut where needed. And a chamfer for the thread start.If you just want to model a thread you need a sketch with a centerline for it, then a cross-section of the thread profile that matches the specs for that thread type. Getting thread spec manuals has varying levels of difficulty. I had specifically had trouble tracking down DIN specs for glass bottle threads a few years ago.
>>1661530>Not really. Difficulty depends on how you want to add them and how accurate you want them to be. For machining purposes the threads in the model aren't important for anything other than visual indication because the spec notes will be followed instead.3d printing thread, not machining. You model what you print, and unless you're using a thread library, it's hard.If you are using a thread library, you probably don't have a jar lid. Or 1/8BSPT for that matter unless you bought the full Monty.
>>1661531>it's hard.Sorry-- not exactly hard. More bloody tedious. And nothing out there deals with really long spirals well when you're building from scratch.
>>1661532Be easy on him, he's probably a Prusa user.

>>1661544I feel you, personally I gave up on the search for good ones.
>>1661495its gizmodorks and I have to assume this is the most pure version of PC I have used because its fucking impossible to print with. My print in >>1661278 failed. Came apart mid print and was still warping even with a 120C bed and a chamber so hot I had to take out my digital thermometer because the screen was turning black. This filament was a waste of money
>>1661531>If you are using a thread library, you probably don't have a jar lid.>>1661532>And nothing out there deals with really long spirals well when you're building from scratch.I use three different CAD packages regularly for various reasons and they all treat threads and helical paths slightly different. Alibre requires you to make the sketch profile you want to use to generate a thread, so you have to draw the whole profile using toleranced dimensions for minor and major. And then you have to make sure that no part of the sketch goes outside of the intended pitch. I've done this more than a few times to make non-standard (sloppy) threads for printed parts that need to screw together after printing without any clean up and with lower potential for galling.In Solidworks the thread wizard does most of the work for you, but you might have to clean up the thread profile sketch after the fact if there's nothing ideal in the library.What I forgot to mention and what is the absolute easiest way to go about this is to just utilize the McMaster-Carr catalog. You can download a model of a fitting, plug, screw, or other piece of hardware that includes the thread you want to model. Then simply use that model as a boolean subtraction on the part you want to print and you've skipped the whole process of modeling the threads from scratch. This works perfectly fine for tapered threads which are an absolute bitch to model accurately.If you need to change the thread fit you can just scale the McMaster part model a tiny amount on diameter only to make it a sloppier tolerance.

I don't get it.I have the following gcodeM42 P4 S255G00 Z0G00 X50.828810 Y0.199180M42 P4 S0G00 X0 Y0.199180M42 P4 S255G00 X50 Y0.199180M42 P4 S0G00 X0 Y0.199180M42 P4 S255The m42 turns a pin ON or OFF, if i enter the M42 commands into the terminal in octoprint manually they work flawlessly, but if i execute the gcode above, then the pin goes LOW for a fraction of a second and then remains HIGH for the rest of the printhow is that possible?the gcode is simple as fuck, turn pin on, move right, turn pin off, move back, turn pin on, move right etc
Yes! it's working!My laser attachment is performing beautifully.Look at that shitI turned my 3D printer into a .... laser printerbadum tssexcept this one doesn't need any toner
>>1661750are you still doing that retardmode shirt with the mirror bed?
>>1661753I am not going remove the bed surface every time i want to use the laser module.I just placed a piece of wood over the mirror to cover it which is enough since the laser won't burn through it
>>1661750This would've been a more appropriate test image
>>1661750What a waste of a first print.
>>1661692Except literally everything useful
>>1661544So what would you rather print?Legitimate question
>>1661544To be fair, short of a professional level, that is 99% of the usefulness of an SLA printer... If you can get good at painting them people pay out the ass for those minis.
>>1661874What are you planning on printing that you cant print with a setup that is good enough to make minis?
>>1661940something bigger than a mini.
>>1661944I dont see why that would be a problem at all.
>>1661960SLA printers are... small. Unless you want to drop near industrial dosh.
>>1661750Despite your absolute shit choice of first image, I'm curious how you added a laser attachment. Most guides I've seen are basically pic related where it says "get a laser diode and then here's your first result"
>>1661976IIRC we had the L-cheapo fag here on /diy/ some time ago.http://www.robots-everywhere.com/re_wiki/pub/web/Main.LCheapo.html
>>1661976Despite your shitty taste in memes, I shall graciously answer you.It's simple as fuck.First you buy a laser with a driver on ali from chinks. 2W is enough to engrave most shit.Then you devise some way to attach it to the extruder, 3d printing an adapter is the best way, but you can ghetto rig it with duckttape if you are lazy1/2
>>16620542/2then you need to find a free PWM pin on your printer's board and attach one wire to it and a second wire to a ground pin.Then you will connect those two wires to the TTL pins on your laser driver.Personally i am using optocoupler separation when itnerfacting any outside electronics with my printer to avoid accidental nasty shorts and shit when you are using multiple devices with separated non isolated power supplies, better safe than sorry.My chink driver board that came with the laser died literally after 5 seconds of using it so i had to build my own from an lm317 instead, which is surprisingly easy to do, but i doubt you will be unlucky enough and have to do it as well.And thats it. After that you turn that pin on or off with the gcode M42.If you use duckttape you can do the whole thing in 10 minutes.
>>1661893Maybe something actually practical like hip replacements for example?
>>1662059You're hoping to make an amateur hip replacement and the people making minis are the autists?Surely you're aware there are several million dollar SLS printers that can produce titanium and even tungsten parts yes? Issue is I don't think they have a degree of accuracy down to make something like a hip joint without quite alot of post processing, and I don't think the final results are as strong as traditionally produced metal surgical implants.
>>1662059As of now you should see 3D printing for bio mechanical in the sub $3000 range as quick and relatively inexpensive prototype creator. The beauty of it is that quality printers are becoming cheaper. I mean don't let me stop you. Go to the /sci/ wiki and pirate the anatomy books there. Bone is honestly an amazing material. It would be interesting for the SLS technology to create artificial bone.
>>1662065I am saving up money so in couple of years when the 3d printers advance more, i can buy one like they had in 5th element and print myself a waifu
>>1662067Better start on working on now so you don't have to play catch up to the tech whet it does come out. Get to it.
>>1662064>Hip replacementsWait you mean like REAL hip replacements? Not prototypes? That's sketchy as fuck my man. I don't think I'd put my life on anything 3D printed.
>>1662064>Issue is I don't think they have a degree of accuracy down to make something like a hip joint without quite alot of post processing, and I don't think the final results are as strong as traditionally produced metal surgical implants.Racecar anon here, we had a sponsorship with a company that made 3D-printed implants, mainly facial (dome, jaw, sockets, etc.), while they weren't talking as much about joint replacements their implants that keep your brain inside your head very much are as strong as traditional methods, if not stronger, and fit much better even without post processing. They've developed methods to go from MRI to CAD to CAM, and the kind of fit they can achieving is great according to most doctors. I'd severely doubt bearing surfaces and movable joints though, although they did a few jews including sockets and apparently they work well.
>>1662079Not sure what the fuck he meant. Theoretically an Ender 3 could do prototype hips. I would agree though, if the products of SLS printing are anything similar to those clays with copper/silver in them that you can make shit out of then burn the clay away to have a solid metal object then they are likely brittle.
>>1662079>>1662082It would be much easier to cast a positive and lost-PLA cast it.
>>1662083Do you actually have experience with lost pla? Ive been dicking around with trying to forge flat ring blanks for another hobby I have so I can buy bulk smelting metals instead of premade rings.
>>1662085I actually have two PLA intake manifolds for an Indian at a local artist, who is going to cast them (one brass, one aluminium). Cost me 50 EUR for the two of them which is a helluvalot cheaper than CNC milling, it'll just need finish machining (clean up the inside, plane the mating surfaces).
>>1662079You were literally 3D printed from base elements by your mom's uterus
I have been using Solidworks for four years now, have gotten several certifications on it and it's by far the quickest program for me to work with thanks to all that experience. However, I'm graduating university, probably going to work 4 days a week as an employee (already have offers lined up), leaving a day or two for technical consultancy and prototyping. Leaving uni means I lose my SW license, buying one for a small business is cost prohibitive and I'm not pirating it because on two seperate occasions SW went in dry with no lube on people that were using it pirated versions for their own business, costing them several thousands.So, what's the best program to replace SW with? Fusion360 seems attractive for a small business and I've tried it, but the workflow just isn't as smooth as SW for me. What other programs should I consider?>tl;dr What is best CAD to replace Solidworks?
>>1662131literally first post recommends Blender and Fusion360But if you already know how SW works, you can literally use FreeCAD. it doesn't matter at this point, you already know how 3D CADs work all of them behave in similar way.
>>1662133I made the OP and recommended Blender and Fusion on behalf of other anons mentioning them ITT in the past year or so. Yet, they seem clumsy compared to SW. FreeCAD seems even more obtuse.
>>1662137Inventor is Autodesks copy of SW if you want actual SW alternative, there is a change that they will break down on your company too if you use their software for "free" but unlike SW you can actually get fully working software by telling them you are still in education.If I understand you correctly and you want an actual CAD for engineering purposes and not just for 3D printing.
>>1661091>heater right next to your drivesmaking me nervous there anon
>>1662081wow. imagine using jew so much autocorrect puts it above test or jigs
>>1662131Inventor's not bad. I transitioned pretty easily from SW to it; each program has its quirks and features but you get used to it pretty quick. Still costs a pile of money, though.Fusion is vaguely comparable in that it's an Autodesk product but it's even easier to pick up than most others due to its "user friendliness", which is sometimes a downside, but it's free if you make under $100,000 a year with it, but it sounds like you've already investigated that.>>1662133FreeCAD sucks ass, though, all things considered.
>>1662593>FreeCAD sucks assthis true and sad.how can it be unfucked?
Is the possibility of making some side cash with a 3d printer possible or did people saturate the fuck out of the market with stupid shit?
