I've been wanting to get a resin printer for making base bodies for dolls. I looked into the Photon D2 and it has amazing detail but the build volume is lacking for me. It would still be able to print some 1/3 scale dolls without splitting parts but other printers I've been interested in are the Mono X2 and Mars 4 Max that can do up to 1/2 (~90cm tall) I plan to try mixing Siraya Tech Tenacious or 3DMaterials Superflex with Resione F80 or 3DM SuperElastic into my dolls to make them durable and squeezable. People that make functional parts out of resin recommend Siraya Tech Blu to achieve a similar strength to filament which could be useful for making armatures too, but I'm just gonna stick to BJDs because I only want to make cute dolls and outer shell parts people can use in their robowaifus to make them cute.

>>28002 Great advice Anon, thanks. >>28007 Good luck with your printing goals, Anon!

>>28002 >This level of hardness is what you should expect from strong resins. Compared to ABS’ average Shore hardness of D 100, the highest measurement on the Shore scale, you can see why these resins are known as ABS-like. >In essence, strong resins are a lot tougher than their standard counterparts, but are still not quite as sturdy as standard ABS filaments. Anon stronger than average resin could mean stronger than fragile... I am using pla+ and its not as sturdy as I'd like it to be. Please do tell the results after you buy the printer however. I don't see whats being gained with your gamble however.

The extruder wasn't working so i swapped for a new one and now that one doesn't work right. This is miserable... but if i can't be an ender 3 technician i sure can't be a robowaifu technician...

>>27798 Thanks again for doing all of this.

TPU is the GOAT for battle bots, keep that in mind: https://youtube.com/shorts/wjkdCdX5Xmo - It's also very resistant against abrasion, which might make it even a good material for some gearboxes or at least some elements of it.

Oh, and we've got desktop silicone printers: https://youtu.be/4aMTPGpRYY0 https://ieeexplore.ieee.org/abstract/document/8404935 Unfortunately, price will be 5-6k and for the early prototypes it's rather 13k. >Additive manufacturing has a wide range of applications and addresses many challenges inherited from conventional molding techniques such as human error, multistep fabrication, and manual handling. However, 3D printing soft functional robots with two-part platinum cure silicones requires development to match the material performance of the molded counterparts. In this paper, we present a custom 3D printer and an extrusion mechanism capable of 3D printing soft functional robots. Moreover, we compare the performance differences between our 3D printed soft robots and molded counterparts via lamination casting and lost wax casting. We validate our results by conducting multiple experiments such as blocked force, bend angle, failure pressure, and dimensional quality analyses. We demonstrate that our method enables 3D printing of soft robots that can perform better, or match the performance of molded counterparts while being more reliable and robust with the usage of the same materials. https://www.3dsiliconeprinting.com/ OT (I hope), Radiation cleanup related: https://www.frontiersin.org/articles/10.3389/frobt.2019.00040/full

via >>30501 >This article demonstrates a two-step method to 3D print double network hydrogels at room temperature with a low-cost ($300) 3D printer. A first network precursor solution was made 3D printable via extrusion from a nozzle by adding a layered silicate to make it shear-thinning. After printing and UV-curing, objects were soaked in a second network precursor solution and UV-cured again to create interpenetrating networks of poly(2-acrylamido-2-methylpropanesulfonate) and polyacrylamide. By varying the ratio of polyacrylamide to cross-linker, the trade-off between stiffness and maximum elongation of the gel can be tuned to yield a compression strength and elastic modulus of 61.9 and 0.44 MPa, respectively, values that are greater than those reported for bovine cartilage. The maximum compressive (93.5 MPa) and tensile (1.4 MPa) strengths of the gel are twice that of previous 3D printed gels, and the gel does not deform after it is soaked in water. By 3D printing a synthetic meniscus from an X-ray computed tomography image of an anatomical model, we demonstrate the potential to customize hydrogel implants based on 3D images of a patient’s anatomy. https://pubs.acs.org/doi/abs/10.1021/acsbiomaterials.7b00094 >=== -patch crosslink

I found what might be an excellent low cost resource. Used or refurbished 3D printers on ebay. I found by accident looking for 3D stuff on ebay. Creality has their own ebay store where they sell refurbished printers. The bad part, Creality's quality control sucks, bad. These are printers someone has already returned and while they say they refurbish them, some appear for the bad reviews to be thrown in the same box and shipped out again. So why bother? The VERY important point is because they are refurbished ebay, allstate insurance has a two year warranty on these things. They also tend to be slightly over or around half the cost. Still you might say that's a bad deal but if look at the reviews on Amazon the negatives tend to be Exactly the same percentage as they are on the returned, refurbished printers. So you're really not taking much if any more risk and you're getting a much better warranty. Another way to think of it that for any part that may be bad you could upgrade to a far better one, make sure everything works and still be out less money than the one bought new from Amazon, while taking no more numerical risk of getting a bad one. Now it would be nice to have the funds to buy a perfect printer but to get a really good one you're talking $500 or higher. Base model ender 3's you can get for around $100 used. I like the ender 3 V3 SE. I like the dual screws on the "Y" and "Z" axis. This gives you a great platform for stability and the direct drive extruder is far better as opposed to boden cables. Boden cables are likely to be a problem if you speed it up to go faster. The cable friction causes problems though at low speeds it's perfectly fine. SE, not the fastest, but I think you could add parts over time and make it better and better. Creality is not the best but they have so many sold there's a pile of hardware and software add-ons. So over time you could make it what you wanted while cheaply getting into it.

>>30917 Interesting idea. Thanks, Grommet! Cheers. :^)

TinyMaker : moe resin printing for every Anon! :D https://www.youtube.com/watch?v=6vfQrYthlw0

>>31481 That's very cool. I see resin printers as the sort of final step in making molds for parts. Rough it out with filament printers then when you're satisfied use the better resolution of the resin printers to make master molds. I'm not sure but this might have better resolution, even as limited as it is, than a typical low cost filament printer. You could always print a bunch of small parts and glue or connect them together to make whatever size you need. Slow but, cost, cost, cost is always a problem. The bigger $500 resin printers are nice but if you can't afford one they are of no use.

BTW I see the board is back to the old style, for me anyways. It's so much better.

>>31498 >fine-resolution/mold-making Yes, I agree. For many one-offs, I almost think vacuum conforming plastic sheets may be the best approach -- especially for shell parts. But for the intricacies required for good joint components, sensor actuators, various fastener scenarios, etc., then resin printing can be just the thing (KEEP YOUR RESIN PRINTING AREA WELL-VENTILATED, ANONS!111ONE!!). Once we go beyond boutique-scale garage shops, then mass injection-molding contracts may be the best route. But till then, I suspect that filament-based printing will still rule as king for most of us Anons. --- BTW Grommet, your great inputs across the board here over past month or so have been much-appreciated.

3D Printing Smart Clothes With a New Liquid Metal-Alginate Ink https://www.youtube.com/watch?v=hyEGK8NmCiI I've been binge watching 3D metal printers. The numbers are exploding with all sorts of methods being used. The laser powder types are being eclipsed by faster, cheap solutions. Some are electromagnetic metal droplet pumps, tiny droplet piston pumps, high velocity particle jets etc. There're blowing up and the cost is plummeting. Now the new ones are not as good as the standard laser metal particle but faster. I can see these others getting better and better. And a lot of them use standard aluminium or other metal wire. No special powders. If you look at the tech the cost has a long way to fall before you run into rock bottom material cost constraints. Eventually you could easily get 3D metal for the cost of high end plastic filament printers cost now.

I've been every so often looking at 3D plastic filament printers. I've thought of all sorts of schemes to get something low cost but the horrible quality control has always held me off. Like I need more things to work on. I'm covered up already. I don't want to spend hours tinkering with these and until now quality cost a good deal of money. BUT...Bambu Lab A1 Mini is now on sale for $200. I've never heard anyone, no one, say anything much bad about Bambu printers but they were always very pricey. With this I think they will either kill the competition or the competition will have to up their game substantially. In almost every case, well every case I've seen, people say you plug this thing in, it runs calibration that covers deck height, motor vibration. printing head vibration, belt tension, and it does all this automatically. And another thing it has is some sort of exact plastic flow sensor that tells the machine exactly how much plastic is flowing so you get a good even flow by using this feedback mechanism. It also has wifi so you can run it from your personal computer or even your phone. It has a camera so you can remotely monitor printing with even a time lapse function that records your print. WHAT THE HELL CAN THIS THING NOT DO. Can it make bread, cook a stew... Well it doesn't print large sizes. It is limited to a 7" x 7" x 7' area. I have a very strong suspicion that they are using these as loss leader market tools. The bigger ones jump up in price fast but once people get some thing that prints accurately, doesn't constantly break, is as fast. or faster, than most all other high speed printers and cost less, with, mostly flawless printer...consistently, then people will be spoiled. And if they need bigger prints will swallow hard and pony up the bucks to by their more pricey models. I've seen tons of people who say they have years of experience of working with the other brands and they got really good at tuning them but when they got a bambu it was a revelation, as there's not much more to using them than turning them on and getting good prints. Not that they can't mess up but all these feedback loops they have makes for a much higher print completion and quality. For us 7" size is fine. I envision joining parts like Japanese or early European wood joinery. The joints, if done correctly, are extremely close to the strength of a solid piece of wood. Same would apply to plastic. A few examples, https://i.pinimg.com/originals/ef/59/9f/ef599fffcfcc0400c2fbf6f5ed99a5b6.jpg https://avbarn.museum.state.il.us/sites/default/files/images/Collins_Ric_IMG_35.jpg and one I particularly like the scissors joint https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Ftse2.mm.bing.net%2Fth%3Fid%3DOIP.iUE1sdMrS_bIC0VWC4z8oQHaEK%26pid%3DApi&f=1&ipt=3c6ebc52e622b48d00bb04f2a77c6dc2c58011bb1b566667d1c354ceae06f317&ipo=images With software making these joints it would be a breeze compared to whittling them from wood. I suspect once you had a system to do so, splitting these into smaller parts that join solidly would be fast and easy.

>>31664 Sold, Grommet. I'll be getting one before long and we'll give 'er a spin. I'll let the board know. BBTW, you should be in sales, Anon. Cheers. :^)

>>31664 >BUT...Bambu Lab A1 Mini is now on sale for $200 Unfortunately, the cheapest I'm seeing rn is US$349. , Grommet. Can you bookmark your pricing link and share it here please? I imagine that's still a good deal, but still $150... Thanks, Anon. Cheers. :^)

>>31683 You have to scroll down and around. What they are doing is the page you land on for the A1-mini has the package deal of the A1-mini + a four color printing optional accessory. They have a retarded number of scripts on the page and you have to scroll around to find the $200 A1-mini alone. Maybe this link will work, https://us.store.bambulab.com/products/a1-mini?variant=41513493627016 The extra colors are not a bad deal at all. In fact a huge bargain. I could see having an additional color being an asset. Especially if you use one color for base and then a water soluble filament to make voids. One use for the multi-color is to to print spots with the .2 mm nozzle. So you print a translucent white but below. or next to, print various shades of red or pink. Like magazine printing from a distance you have a mixing of the colors to make shades. So with a white, black or brown, red or pink, maybe a yellow for Asians you could have realistic skin tones. If you can at all afford it I would recommend the multi-color kit, even if you see no use for it immediately. I read they were difficult to acquire if you don't get them together. But you can get around with just one color. My sweet spot for buying these is $200, maybe $250. Look at this video from a long time 3D printer user on the Bambu A1-mini who has used all sorts of printers. It's good and look at the comments. https://www.youtube.com/watch?v=vBQ-QfcY3Qs I've been also looking at resin printers. I don't know how good these are. Brief reviews seem to be ok.

The resolution is 28.5um (.0285mM) (0.001122047 in.) This is very close to ten thousandths of an inch which is considered good accuracy for machine work. Even if the resolution is actually twice that due to manufacturer inflation, it's still good enough for us, at $200. The Egloo Mars 4-9K $250.00 USD $199.99 USD sale price 7-inch 9K mono LCD, 8520x4320 resolution XY precision 18um (.018mm) (0.0007086614 in.) is so close to ten thousands of an inch. If it's even close to specs then it's production level. The more pricey ones may be accurate to ten thousands of an inch even if they are lying a little about the resolution, and only $100USD more. So we're talking about production level models. In my mind you use these for molds, or make molds from them. So you rough out designs in the Bamboo and when you have what you want, resin print it for mold production. Linking these together means any size you want can be done with extra time as the deficit. If fact for most needs the Bambu with a .2mm nozzle, and good deal of time, would be good enough. I expect that you could easily get .6 mm resolution with a .2 mm nozzle even with glitches. Maybe better. The new printers are really getting exciting. Cost and capability wise. The possibilities are endless. BTW do you know if we will "ever" be able to upload pictures and files directly here??? And what would it take t do so?

I can't help but wonder if you couldn't make a .1 mm or .05 mm nozzle, maybe even smaller, and slowly, ever so slowly print with the Bambu to get super accurate prints? I see no "physical" reason this could not be done. I don;t know what the ultimate stepper resolution is. I suspect it's high at low speeds as the stepper uses difference wave forms to create partial steps, I think. I know this can be done. Bambu, according to users, appears to be responsive to customer request and supposedly has so far been constantly updating their older printers software. I think it could be a great selling point to have this super resolution mode as an option. Maybe charge more for nozzles.

It seems someone is working on a consumer grade SLS printer. https://www.youtube.com/watch?v=OQ6DYJtn7Bw It seems interesting, but at it's current backer price of ~$3700 USD I don't know if it's exactly worth it. The machinability of printed parts is what catches my eye the most.

>>31805 >consumer grade SLS printer. That would be wonderful. Thanks for the update, Anon! Cheers.

Well this sucks. I have been scrimping to buy a top-end Bambu Labs printer for detailed robowaifu parts work. Now I find out they are forcing the printers to be on the cloud before printing. Any solutions to this issue (that aren't just 'lol so what?' :D, Anons? Their advanced features are why I've been waiting until I can get one. Any other competitors that won't try to strongarm this type of GH-style sh*te on their users?

>>35889 >top-end Bambu Labs printer for detailed robowaifu parts work. Now I find out they are forcing the printers to be on the cloud before printing. I'm not so sure this is true. "...What is LAN Mode? LAN Mode is a feature that allows Bambu Lab printers to work in a local area network, and communicate with the slicer for sending files and monitoring without requiring internet access..." https://wiki.bambulab.com/en/knowledge-sharing/enable-lan-mode https://www.reddit.com/r/BambuLab/comments/152xlpe/bambu_lab_life_without_internetcloud/ I don't have one yet but my opinion is to buy the mini. Any larger parts can be cut in smaller sections, joining brackets added, print and then the pieces glued together. My reasoning for this is I do not expect to have any parts I make be made of filament. All of them will be made in 3D printed molds used to make composite parts of other materials. Most filaments engineering wise cost too much per pound and are not all that good. I think you can use epoxy, polyester and other resins combined with other fibers and make something far cheaper, better, stronger. There's also the benefit that printing mold shells is super fast. So you can rough in what you want. Then use cheap prototype metals/plastics to fill the molds to see if it functions correctly. There's metals and plastics that melt in boiling water. One plastic is, https://en.wikipedia.org/wiki/Polycaprolactone Also called, ShapeLock InstaMorp Moldable Plastic Thermoplastic Beads Polyshape Polymorph Hand moldable Plastic This plastic is supposed to roughly the strength of nylon, which is good for prototype testing, but melts at 60 °C (140 °F) (not the final part because it melts but good for testing) One low temperature melting metal is, cerrosafe. There are many others at many price and melting points. https://en.wikipedia.org/wiki/Cerrosafe To make fairly strong parts at a low cost you can use Fumed silica mixed with polyester resin for a smooth surface coating then cram in fiberglass cloth or glass fibers soaked in polyester, epoxy or other resins. Any number of natural fibers will also work. https://en.wikipedia.org/wiki/Fumed_silica Polyester dries quick and is super strong. They have many over fifty year old boats made of this sort of stuff that are just fine. And even stronger is the same with epoxy but it takes longer to cure. and might I ask, what is all this and what does it do??? >>35889 >>35890 >>35891

After I wrote the above I thought, is fiberglass stronger than human bones so I asked and the AI "DuckAssist" said. DuckAssist BETA "Fiberglass can be very strong, with some types reaching tensile strengths of up to 2,358 MPa, which can be comparable to or even exceed the strength of human bones. However, the specific strength can vary depending on the type of fiberglass and its construction."

>>35889 and I forgot to ask how do you add this code or deal with it?

>>31805 >SLS printer Thanks, very interesting. More options and progress is always better. >>35880 Imagine if you already had it, and now they would do that, and there was no way to work around. You might have dodged a bullet.

Elegoo has a new x-y printer. Supposedly x-y more stable the Centauri. Is this a a bambu killer??? Babbu labs has been making the best printers because they monitor exactly the flow from the nozzle and have precise inertia calibration. They calibrate the print heads motion so they can print faster by knowing exactly where the head is. The new printer is $200 (preorder) AND it has the space of larger printers than Bambu's smaller printer. Print Right Out of the Box Full-Auto Calibration, No Manual Adjustment CoreXY with 500 mm/s Velocity 20,000 mm/s² Acceleration Build Volume 256 × 256 × 256 mm This is the same specs as Bambu. Time will tell but this appears to be a good move. They "say" is has the same calibrated motion control. Now the $200 is for the cheapest. It has a die cast frame which good but no glass covers for the cheap one. The expensive one is $300. Are they both the same except for glass. Don't know. I suspect I could find some glass for less than $100. Bambu has lately been trying to tie thier printer to Chinese servers one way or another. If Elegoo is able to make something that works as well it kill their plans. People will abandon them. I obviously don't know if this works as well but you can clearly see they are following Bambu and attempting to take their business by copying their tech that makes Bambu so good. Even if they are not quite as good I could see software alone upgraded could make the printer better even if it has a few false starts.

Forgot https://us.elegoo.com/products/centauri

Elegoo Centauri Max. Nozzle Temperature 320 °C The specs on this thing is really impressive. Higher temperature nozzle means ABS, maybe nylon printed. specs Filament Type PLA/PETG/TPU/ABS/ASA That's 99% of what you would need to print with, for me, it would all I needed.

>>37065 >>37066 >>37067 Thanks for the information, Grommet. I'm currently thinking about printers in the mid-term. I'm extremely disappointed to have to have eliminated the top of the line Bambu Labs printer from my short list. They're dead to me now tbh. Any information from Elegoo about following a similar control approach for stable printing that Bambu uses? Any other printer companies doing something like that? I'm probably looking to get a printer in about 6 months or so. Cheers.

Elegoo Centauri has good printing reviews from people who have used it. They compare it to the $1,000 Bambu X1, favorably. And if that's not enough. Someone has a metal wire laser printer. Prints 3D with wire. WOW! Starting price at $600 USD. Double wow! Of course that's the low end. I have no idea what you get for that but if it just prints metal that would be good. It can be set up with,maybe comes with, machine tooling to finish it. Meltio’s M450 https://www.3dnatives.com/3D-compare/en/3d-printers/m450/# Apparently the US Navy has one on a ship to make ship parts. This opens up real possibilities. If you don;t have the machine tool part with it, you could make! Maybe need a drill press as a temp lathe and a few cutters and vise and you could make most anything.

I read that Elegoo is using a tuned version of Klipper. Klipper takes momentum and the mass of the print head into account to predict movement. The reviews on it say they were getting fast consistent prints. I expect that it's likely not Bambu but...it's not $1,000 either. You could probably slow it down slightly and do just as well. The reviewers said they were getting bambu quality. Of course will Elegoo fuck up the quality? I can't answer that. I think for $200 it's well worth the risk. I see a package deal including two rolls of PLA, a spare hot end extruder (you can get it in 2mm) and three build plates for $245. That's a sweet deal. Another major company Creality, I have never ever heard anything but poor control over their quality. It's random. Some people get stuff that works and some have nothing but trouble. This is one of the reasons I like Bambu, everyone spoke highly of them. Next to no bad machines. Plug it in and go. BUT this is such an advance at that cost, I think it's worth a gamble. It's prepay now and won't ship for a few months so I don't know if this price will stay the same. I don't know about all the others. If you want a sure thing, or most likely a sure thing, get the much smaller bambu mini. It's $300 and from everything I read works well right out of the box. But it has lower temp and much lower features. Tough call. My view before I saw this was bambu mini for $200. Volume is not everything. You can print in pieces and glue or clip together. You can 3D print the connectors in the parts. I expect that the printer is just to make molds or should be. It would take forever to make all your actual parts and be very costly. But shell molds, super fast and put whatever you want in them.

One other thing the reviewer said Elegoo used Klipper on other printers and did not seem to have it all together but this printer they said they had it working correctly. Of course they could be lying.

One last thing, no cloud. All local.

>>37074 >If you want a sure thing, or most likely a sure thing, get the much smaller bambu mini. It's $300 and from everything I read works well right out of the box. Thanks for the advice, Anon. But as I said before, they are dead to me. I value my privacy much, much more-highly than I do slick & quality printing. I think I'll try the Elegoo you mentioned. Thanks Grommet! Cheers.

>>37077 I made a mistake. Bambu mini $200. I also do not think Bambu "makes" you use the cloud. I may be wrong but there's a setting to change it to local. I've seen the setting in their manual but I'm not sure if this has changed. I suspect that Bambu if they force the cloud will lose a very substantial amount of their business.

I'd been saving up slowly to be able to acquire the X1-Carbon + the AMS & 4-spool multi-print combo system. Now that money will be going to some other printer manufacturer. Try to strongarm me with kikesh*te-style globohomo privacy-invasion tactics, will you!? >:( <---> Anyway, thanks for your latest research ITT, Grommet. Cheers. :^) >=== -fmt, minor edit
