Here is the ring I ordered! First, the design: And second, the printed resin! (Sorry for poo poo iphone camera quality) Everything turned out exactly as I had wanted I'm doing this a bit different than normal so the next step is to make wax reproductions of the resin and then cast those in silver, and blacken the low points. Should look pretty cool when it's done

techknight posted:Edit: Interesting...but i guess not totally unexpected. Even buying the kit from him still means you need to source a ton of parts from other places for the same cost as a full kit parts like the frame, motor and projector. Or so I would think? This does open up possibilities for people to create cheaper frames though...

My Rhythmic Crotch posted:I'm looking at the prices posted up for Veloso's printer and I'm shocked. They are well beyond what I would call "a little expensive"... Not to mention you can't even see an itemized BOM without paying $160. Lame. Maybe I will follow Lemon Curry instead. I feel the saaaaaame way. That or someone will buy the BOM and tweak so they can release it as open source. I just cant believe this: 1) Software and controller board. 2) All necessary motors for the printer 3) The linear actuators 4) Power supply for the controller board and motors 5) Building tray 6) Building head (area that the object is build) costs $2000. Especially from what i've seen of these printers and it only seems they actually need to move in Y. I thought maybe the precision is what makes it so expensive, but ultimakers do that on 3 axis and they dont cost 6 grand Mind you I am certainly no engineer so I could be way off base here. ninja edit: And after indiegogo that's going to cost 2700

A lot of folks don't agree with his pricing, or assumed that his efforts would be at least partially open source, but I wouldn't go so far as to call him a weasel. Yea I guess that was my bad. But I felt the same way too, every way he went about it seemed like he was for open source and the community only at the *seemingly* last minute to now be all about profits and 300k in a month. Either way whats done is done and him starting his project (and the way he finished it) encouraged lots of others to as try well and that is a good thing.

I think he's made an additional 200k in the past week just on last minute orders! And the resolution he is achieving is unbelievable. He thinks there is no reason they couldn't slice it into thinner than 25 micron layers and I (assume) the only thing stopping the x/y resolution is the projector, which could be upgraded for stupid insane resolution in all directions. That combined with perfect burnout tests for casting makes me one very, very happy person.

Not an Anthem posted:What photopolymer dlp printers are out right now? I recently saw a bank of them in a manufacturing context that was very, very unexpected and it looked slightly like the veloso's. I want to purchase one, I remember veloso was on indiegogo but these, while looking like something built by an engineer from a kit, didn't look like the velosos that I've seen photos of online. Are you talking about the B9 creator? http://www.b9creator.com Go to the kickstarter for more info, this is pretty much veloso's except you can switch between 100 and 50 micron resolution and the resin used in the B9 is CHEAP. If you see the little Eiffel tower he made it apparently cost 10 cents in resin. He's filling out kickstarter orders now, or early august and then will have a webstore up to accept orders for more kits. Can't wait! Also if your production prototyping ever needs metal pieces, they did full burnout tests and the resin can be cast pretty much just like wax.

TerminalSaint posted:You could probably print one of the quality you'd find in a hardware store or walmart no problem, but with a high-performance airsoft gun you'd run into a few problems. Without a soft rubber hopup bucking you wouldn't get a good airseal or backspin on your BBs. A metal barrel is pretty important for accuracy and velocity. Durability would be an issue too, even metal gearbox housings can be prone to cracking in high FPS setups. Ah yea, I guess there is a lot more to think about than just printing the plastic parts. SILLY ME. Until then, we can print little catapults and desktop trebuchets because we don't need no stinkin' technology to fire miniature projectiles! I really want the B9 store to open up I'm all ready to purchase one! Take my money dammnit!

Linux Assassin posted:Casting, printing, build size oh my! The issue i see with your points in general, is it's a mix between a fun 3D printer that needs tweaking and something that can output consistent size and detail. Wanting detail and a large build volume is something that's mostly limited to the super fancy expensive printers (except maybe the makerbot?) In terms of casting, I have no idea about the burnout properties of abs and pla. I know that the B9Creator tested their resin in burnout and it performed perfectly, but the build size is small. I guess you just have to choose what you want the most and see which printer can enable you to do that the best. I'm also having problems choosing, I want the B9 but envisiontec just put out a new, smaller jewellery capable printer. These are it's specs: Build Envelope: 1.58" x 1.18" x 3.94"(40 x 30 x 100mm) ERM Pixel Size: 31 μm (0.0012") Linear Z Axis Resolution: 1 μm Dynamic Voxel Resolution in Z: 25 μm (0.0010") to 35 μm 0.0014" (material dependent) Light Source: LED Data Handling: STL Warranty: 2 years in factory parts and labor Footprint: 9"L x 8"W x 24"H (23cm x 18cm x 58cm) Weight: 29 lbs./13 kg Electrical: 110V, 3 Amps Build area is tiny but ohhhh mah gahhhd that resolution/accuracy. It's also $20,000 maybe i'll try and get a small business loan.

techknight posted:Thought I'd share something I'm working on... I really like the Sappho's Head sculpture scanned by Artec, so I've printed another copy at 1.5X times normal to try a few finishing techniques. Did you use primer first? Even a spraypaint primer should help the paint cover more evenly, and help it adhere to the plastic. As for lacquer you can get a spray varathane coating that's usually used for woods but would help protect the paint.

techknight posted:Nope! I have no idea what I'm doing, basically. I'll look into the varathane, and some primer for the next time. Yea primer is pretty key for painting on plastic. Look into tutorials or w.e on painting plastic miniatures (e.g. warhammer) and that should be about the same for painting on the printers plastics

Cockmaster posted:Well, the b9 looks like it's capable of higher resolutions than that thing (50-100 microns in the x/y plane, as opposed to 300 for the Formlabs machine). Doesn't it say the layer thickness is 25 microns though? EDIT: What is the difference between layer thickness and "smallest feature size"?

# ¿ Sep 27, 2012 02:47 |

Cockmaster posted:The b9 can go as low as 10 microns. I assume they will, dlp would cure its resin at one wavelength where the laser would cure it at another (I think.) The goop is 149 a litre, apparently about 16ish cents per cubic centimeter. They say it's about as much of a hazard as bleach, probably shouldn't be washing your hands with it but having it around isn't bad. When it's cured it's apparently safe though. I need sub 40 microns (lost wax casting puts about a 40 micron texture onto everything) so anything lower than that is cool but not entirely necessary. I wish I could see tests of a layer thickness of 25 with varying x/y resolutions to see how much it actually changes. EDIT: Looking at the fancy printers they don't seem to have a "feature size" or X/Y resolution. It does however give an X/Y/Z dpi, can I convert that somehow to x/y resolution?

Cockmaster posted:I wonder what sort of print quality you could get if you built something like the B9 printer but with a 4K projector. Though that would obviously have to wait for 4K projectors to get much less expensive and much smaller. Oh snap! This crazy 50,000 printer has a feature size of 67 microns. I would have thought it was smaller. Thanks! I actually asked the guy who made the B9 what the chances were of keeping that 50 micron resolution but making the build area larger and he said the only thing that was limiting him was the fact that he would need a 4k projector that he would then modify for the short distance.

Sagebrush posted:All of the industrial-grade machines are that way. I think one of the test parts with the Objets is a clear piece with internal geometry and you're supposed to fill it up with colored water and make sure it flows through the internal channels properly. I have a friend who worked with large SLS machines for a long time, and when those have to be calibrated you have to build a special part that takes up the entire volume of the machine (mostly hollow, obviously) and measure the thickness at different points. Then on the bottom of the part there are all these little cantilevered pieces, and you're supposed to measure how much they deflect before breaking off to see that the machine is fusing the powder correctly; the wrench you need to do the bend test is printed as part of the test piece and you snap it off to use it. Whoaaaaa that sounds pretty cool with the coloured liquids. At least they made maintenance day (every day?) seem fun haha.

B9 released a new resin made for printing out fine models for game enthusiasts as well as model train builders etc. Got a bottle of it and decided to give it a whirl, sculpted a hellboy face with some hair and ear detail as well as the horns to see if it got them all nice and crisp. Holy hell. This stuff is nuts, printed at 50xy and 20z: I don't know what wizardry these SLA printers are using to get rid of the build lines, but especially in this case it works very well. Print took about 2 hours, as opposed to my normal hour ish.

Sagebrush posted:Optical physics. The extrusion from an FFF printer is a hard-edged cylinder*, while a laser spot (or the edge of a masked light source) is a nice smooth gaussian fade. That helps the layers blend into one another. I think mine is using a projector, so the light would still be in dots? It probably still applies though, I only know how to print gud, not the magic behind it haha. I read an article a while back about being able to scale brightness of the pixels to smooth prints but it went a bit over my head.
