Also Formlabs resin costs $150 per liter and their tanks cost $100. You cannot use any other brand of resin lest you void your warranty (which is like 95% the reason to own a Formlabs printer in the first place). I have never had a print failure on my Form 2, but the thing is just really expensive to run. For what it's worth, I was looking at switching to that 8k once the early adopter bugs get ironed out.

I'm just grumpy about my one foray into LED/LCD printers with one of the cheap machines available in 2019 being failure after failure because I didn't have the time to approach it properly and nothing would stick to the build plate. The thing came with the usual sample print files and it didn't matter how much I re-levelled the build plate everything would just stick to the FEP and it'd be a nugget of cured resin in the rough shape of the sample print in the vat and jack poo poo on the build plate (so I just initiated a return/refund before that time period ran out and I was stuck with the machine). Also, regarding the Form2, you do realize you can enable Open Mode, right? https://support.formlabs.com/s/article/Open-Mode?language=en_US EDIT 2: Also, some resin manufacturers will have guides posted on how to use their resins with the Form2 system. https://www.liqcreate.com/supportarticles/how-to-work-with-liqcreate-resins-on-the-formlabs-form-2-resin-3d-printer/ Also, there's this option: https://www.protoart.net/cartridge Some Pinko Commie fucked around with this message at 16:42 on Jun 18, 2021 |

It took me like 8 hours, but I’ve finally recalibrated our dual nozzle printer at work. No more rubbing of the prints from uneven nozzles. Prints are perfectly aligned. We’re getting better prints than we got from factory settings. I’m so happy. I’ve been fighting with this thing on and off for like a year.

Yeah for example applylabwork has at least one resin that is a drop-in replacement for formlabs. It works okay, but performance clearly isn't as good and it's one of those super stinky acrylates, but at least it's cheaper (it wasn't worth being cheaper imo)

Just grabbed eternal starlight on quest with some credit and it's the perfect game for VR. Hand controls seem to be their big focus which I didnt like the realiability of vs just using controllers, but what's left is still fantastic. Basically what you've got is a roguelike ship fleet game where you equip weapons/tech to your ships like FTL, then you wander around making alliances and controlling them in full vr You can zoom in/out on the fly with controllers and give flight paths to your ships in 3 dimensions which is something that would suck poo poo if just done with a mouse and keyboard. My only complaint is that targetting specific weapon systems etc is kinda janky. Whatever the 2nd refinement of this is will be fuckin insane. Just something akin to eve online would be nuts

Did you have any vents or are those outside ones just stubborn? i included vents but they all closed up during printing; the part on the right just froze at the narrowest point in the runner, which makes sense because i made em much smaller than you’re supposed to. the left one’s unsecured core came loose and blocked that runner. the center two are basically perfect castings, venting and a less narrow runner would fix things shame that the thread forms are way too rounded off to have much hope of thread cutting, alas. at a bigger scale i could get much crisper geometry. still worth the exercise, didn’t super expect to get perfect hardware from this.

This is probably a long shot, but maybe one of you guys knows more about this than me or knows of some good ressources. I have a window AC unit that is a total lifesaver during summer. Last year I got a complaint about the water dripping down. I tried following up, but never found out what exactly was the problem. It might be a resolved situation. Regardless, I figured I'll design a solution just in case. I created an insert that exactly fits the drain hole just like the hose attachment did. I integrated a bell siphon (I think), so the water gets dumped all at once when the level rises above 1cm. I just tested it by dumping some water in through the grates, and it seems to work perfectly for the most part. I have two things I would like to improve: 1) The stream ends up pretty drippy, is there some way to make it more 'uniform' or maybe just dump it out faster (I don't actually know how to optimize for this) 2) Right now the water is a bit close to the wall, I figure some sort of spout to 'shoot' it out further would be nice. I don't know that much about fluid dynamics, so any help would be appreciated. I have a fair bit of tolerance left on surface areas, so I figure there's a lot of potential for improved flow there, I did no calculating there and probably have chokepoints. My only limiting factor is the outer diameter.

If it's sunny where you are, just set the sealed container out in the sunlight for a while, and pour it through a big paint filter to clean out the cured bits. Any strong UV and a clear container should work if you don't wanna go the "bucket heavy, gently caress lifting this" route. Or, get.one of those UV spots and blast the gently caress out of it for a few mins and filter. You got options.

Deviant posted:i guess i could just blast it on the wash and cure station and filter that Just don't do that in the cleaning bucket with the little wheel at the bottom. That's a setup for a bad afternoon. I left my IPA outside in a clear container for about a week, despite it being sunny and hot it didn't do anything for several days then suddenly yesterday there was a thick film of white goo around the sides of the container and all the IPA in the middle was clear again. I strained it twice and put it back into an empty bottle, I dumped all the goo onto a paper plate and left it in the sun for the afternoon to dry out and then threw what was left in the trash. Cleaning the container afterwards was a pain, since I can't just run it under the tap, more IPA and a lot of paper towels and it's ready for the next batch.

NewFatMike posted:Thanks! I'll think about putting it together despite not really knowing lasers that well. Under typical use something as simple as a cardboard box would work for the incidental reflected light. It would only be a short delaying action if the laser breaks off and dangles around, or other situations where the beam could make direct contact with the enclosure. To be honest, if you expect your laser to make contact with the enclosure you're already doing something wrong. Direct contact with a 15w diode laser basically can't cut though even modestly thin plywood, (say 5mm), and would be my first recommendation for a reasonably easy and sturdy enough enclosure. But it can still char it, and thus plausably produce a fire. You're not really going to avoid the possibility of fire unless you go with metal. This is all kind of straightforward. More likely, you're asking about a window. Unlike CO2 systems, diode laser systems like that are firmly in the visible range. Basically, if you can see though it, be exceptionally wary. Looking it up, I've found that the ortur is a 445nm, 15W. So firmly a class 4 (there was never a possibility it wasn't, given it's a laser intended for cutting) So, that's really what you need to look for, a class 4 viewing widow rated to block 445. An an example without endorement. In contrast, here's something with basically the same example image, but with the explicit warning not to use it on a class 4 system. And here's a class 4 window, but not rated for 445, and would effectively be worthless on such a system. There's also measuring it by optical density(OD), which is how much the material attenuates light. I don't have experience with it, so I can't give practical info. Those sheets are rated at OD5+, as are many laser safety glasses. This might lead you to be live that this is good enough. You should also recognize that a laser 1/10th as powerful would still be firmly class 4, and they're just using that as a guideline that the sheet is good enough for class 4. Does that mean it's good enough for a 1.5w, a 15w, or a 150w class 4? FWIW, my read is basically yes. It's a log scale, OD3 is 1/1000. OD4 1/10000 OD5 is 1/100000. As a reference, a 5mw laser is safe (almost always true, but you can do some other things to make it not) a 15w * OD5 would be .15mw. At least until a direct laser strike burns or melts though the window. Which it may, as you'd be dumping 15w of power into the window. A direct strike on an OD3 would give 15mw of transmitted power.

Eyeballing the Prime Day deals this morning, and if anyone's been on the fence about getting into resin printing, the Voxelab Proxima is going for US$141 right now.

The photon sonic mighty is a little cheaper. It's got a wider/deeper build plate but a slightly smaller z axis than the anycubic. 479 vs 529. That extra 30mm is tempting but I can safely say I don't think I've printed anything that really needed it though. Weirdly enough I'm having my own build area madness. I'm stuck trying to decide between an ender 5 plus and a cr-10 v2 or v3. I kinda wanna just get a regular v2 ender 3 but I really like the idea of having a huge build volume. Dunno if I like it ~300 bucks more though. gently caress it, went with a longer lk5 pro. 276 and it has some great reviews.

I'm on my third one now -- two previous were returned for bad LCDs, and the one I have now is down as well until I my replacement screen comes in.

This is enormously helpful, and I'll be double checking with both the laser seller and probably that website to make sure that I'm choosing the correct window material. Going for an inexpensive plywood enclosure is tempting, but I've had enough time on lasers to know that they'll bite as soon as you look away. And praying that you don't have a fire when you open the lid is a prayer I'd rather not make Thankfully I have access to the makerspace lasers to make the enclosure, so that's a good resource. I'd be willing to host some links and DXFs in case anyone wanted to OshCut or Send Cut Sent their own enclosures once I design it.

For me, any monochrome screen machine that gets a resin leak has always resulted in a screen replacement being needed (unless I have a protector in place). The polariser that is on top of the screen is just so fragile that even great care with a scraper can still easily tear it.

I have tried screen protectors several times on several printers and all I get afterwards are fails, so I invariably rip them off again. What the correct process here? Do I re-level? (I did) Do I up the exposure? (I did not) Does it go over the gasket tape, or do I have to cut it to shape? (tried both) What if there's dust under it? (every. drat. time. )
