>>27783 Thanks for the info Grommet. I'm going to try a new low-end Ender 3-B (220x220x250), and see if that works for many of our needs here. It's well under US$200. Keeping everything (incl. manufacturing) inexpensive for robowaifus for everyman is an important goal for us here certainly a big one for me personally. Cheers, Anon. :^)

>>27783 >3D pens Nostalgic, started out by tracing anime girls. Looks like those posts didn't carry over for this thread. I also posted about using those for welding prints together. 1. Firmly connect parts with clips, glue, pins, etc... 2. Extrude slow and steady at slightly higher heat. 3. Make little swirls, ensure you have good pressure to push molten plastic into the seem. >Drawing meshes Potentially a decent idea. I wouldn't do it as it would take forever. I recommend the Gender 3 V3 SE. I have one and it works a treat. You do need to ensure it is on a stable perch. I put mine on a chair with a loose leg and when printing at 100mm+ walls shows clear ringing and distortion. On a solid base, it can go fast with good quality. SPEED DEPENDS ON FILAMENT, NOT THE PRINTER PETG maxes out at 100mm if designed for it. (No bridging, minimal hopping) 50mm is safe. PLA varies wildly, most can do 150mm. TPU varies from 15mm to 100mm depending on shore hardness and print design. Other filaments generally don't matter. Just bought high speed PLA+ from Creality. Will update on practical speeds for the Gender 3 V3 SE. Any recommendations for test prints?

>>27796 >Nostalgic, started out by tracing anime girls. Looks like those posts didn't carry over for this thread. I was literally copy-pasting posts (+ their images) from the emergency big filedump of the old board's threads that I had saved out to disk one-by-one (during that final, tense, 2 or 3 hours of 8ch's existence on that fateful day [remember, I hadn't yet written BUMP then, and I yet had no idea how to use cURL/wget properly either lol]); over to here one-by-one, by hand, to get this board kick-started again (back on Julay.world it was, actually), after the GH glowniggers (+ their affiliated good-shabbos golems like Cuckflare) killed 8ch. As you might imagine, it was a very tedious operation and at the time there wasn't even any realistic way I could make an appeal here to the old hands to help out (I was the only RW 'survivor' here at first, I think. cf >>14500) On-and-off I spent 2 or 3 weeks at the effort, as I recall things. IIRC, I finally gave out after about 1'200 posts of this sort (and the 'new' board was finally gaining some traction on it's own by then as well). So, there's still around 5'000 posts that I haven't/never finshed posting by hand here from the original board. This is one of the important reasons I pleaded with anons several times to help me figure out how to deal with captchas here; from within my own custom software ( >the tl;dr : b/c I wanted to finally finish restoring the OG /robowaifu/ in a semi-automated fashion, rather than my original 'Ugg the Caveman' way, which would take me literally months to finish :^). The other main reason is to assist us with moving individual posts around today, sorted into their proper threads (similar to >merge, but for specific posts rather than entire threads). This is a high-priority need for both NoidoDev and myself, who both really care about our board being a good & organized robowaifu research tool. Ironically, one anon finally did help us (in the previous /meta I think), but the whole post didn't go through and he never did (re)post the 2nd (missing) half as requested, AFAICT. And you can't use just half of a piece of code. An alternative code post would have required me to learn a whole new language (Perl) just to understand it, and I simply didn't have the internal reserves to do so. Therefore, those 5'000 missing OG posts may never make it over ATP... and I'm far too entangled in other life rn to even properly consider the effort at all (though I could probably push the filedump somewhere for others to do so). BTW, this 3D Printing thread was likely one of the larger OG threads, and so it never got fully-reinstated here (apart from it's OP; I worked from smol to large to get the most 'thread traction' the quickest within the catalog during that initial effort -- posting all the OPs first, then going back and 'filling them in', smol to large). >tl;dr My apologies to you and to all the other anons whose many OG posts are still missing here today. An_effort_was_made.jpg :P >humorous sidenote: IIRC, Robi actually came onto the board sometime during those first few days to find out W*F I was up to -- he thought I was samefagging like a madman, and didn't realize I was just restoring our OG board by hand. LOL. (I think it wound up impressing him, actually.) :DD I remember those. I seriously considered buying one of those pens years ago after I saw your posts, Anon. (I got my first smol 3D-printer instead.) :^) >"I recommend the Gender 3 V3 SE" Lol. Do you mean 'Ender'? :D >=== -fmt, prose edit

>>27787 >Ender 3-B (220x220x250) I've never heard of that. Really look at the Creality Ender 3 V3 SE 3D Printer, 250mm/s first. I've seen them as low as $185 and that speed difference is vast. You likely can most of the time print at 150mm/s reviews say. And if you obsessively tune it you could get max speed of 250mm/s. These new faster speeds are really significant. Changes 6 hour prints to 3 hours or less.

>>27804 It's just the regular Ender 3 (but it's the 'B' model ATP) I think.

>>27796 >I also posted about using those for welding prints together... ...SPEED DEPENDS ON FILAMENT, NOT THE PRINTER... Well I missed both of these things. I had never heard of these pens. I could see uses for them and they are so cheap, you know the old adage money or time. That speed is based on filament I've never heard anyone else say this. I could see this for each printer as each one can only heat and push filament at it's limit. https://3dprintbeginner.com/3d-printer-calibration/ This link looks like the mother of all tuning test printing for max printing. It's really impressive. They have separate prints that you tweak the constants as it's printing to see just what will work, where, with your individual printer.

From doing holograms they used a car inner tube blown up with a large concretepavement blocks or boxes of sand on the inner tube. If it will work for holograms, which are notoriously sensitive, should be over kill for a 3D printer.

Guys. ANYCUBIC Photon D2 Resin printers on Amazon are at a 35% discount after Christmas. This is a good time to get siginficantly better printers. I have two Ender 3 printers that I am going to ditch for these because resin has many advantages. You want the higher print resolution for more detailed robo parts, gears and stuff. More importantly though is the speed. Resin printers are able to achieve much higher print speeds than traditional printers. This is important because you can't make progress if you're always waiting for parts to be printed. You can't rapid prototype if your prototypes aren't rapid. Thread is dead. I'm reviving it. https://www.amazon.com/dp/B0B4QWYBZL?ref=ppx_yo2ov_dt_b_product_details&th=1

>>27992 resin printers are for figurines. Its too delicate for robotics.

>>27992 Friendly reminder you need to keep your printer enclosed as the resin fumes will harm you. As a rule of thumb, if you can smell the resin, it is actively harming you. Don't forget you need a vat of alcohol to clean your prints and a UV curing solution to finish them. >>27994 This is a common misconsception. Cheap low quality resin is indeed fragile. There are many resins with great physical properties that would work well in robotics applications. I'd suggest looking into tough resin. It is worth noting you can mix various resins to customize the desired properties. Mixing tough and flexible resins can result in highly durable parts. https://www.3dsourced.com/3d-printer-materials/abs-like-tough-resins/

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. :^)

>>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?
