instagram won't stop advertising this contour gage to me https://www.amazon.com/Saker-Adjustable-Precisely-Duplicator-Woodworking/dp/B083FBRJPM so idk maybe try that

I have looked at that, but they are way too inprecise and large.

What have people found to be the least smelly resin? I'm currently using gray Siraya Fast, which is much better than Elegoo ABS-like, but my wife still complains occasionally.

SEKCobra posted:The gauge has too low a resolution I guess, my curves are like <5 cm in length. What is the exact thing you're trying to model? Your options for digitizing complex forms are: A) make a series of measurements with calipers, protractor, and radius gauges, plotting coordinates on graph paper or something, then copy those points into the computer and draw a curve through them (or connect them with a french curve and take a picture, etc) B) take orthographic photos of the thing with a ruler in the picture, scale and square up and adjust on the computer, and trace the shape directly in your software (or if the part is small, put it directly on a flatbed scanner) C) copy the curve with a contour gauge, then either measure or photograph it as above D) use a high-resolution 3D scanner to digitize the surface directly.

One of those digitizing pens and judicious use of planes in Solidworks/whatever could probably also do the job, but the setup required to do that would be more expensive than the other measuring tools.

Maybe a photo of what you're trying to apply the cover to could help.

There's also something to be said for running searches on GrabCAD and other 3d model sites to see if the thing you want to make has already been made. But like, just search for the vehicle in question and see what has been made for it. Don't run a super specific search because if someone didn't use one of your key words it won't come up in the search.

I just had my first experience with bad resin (I think). Multiple failures on one machine that looked like resin-on-screen type of problem where some of the print is on the plate and the rest is in the vat. Then all of a sudden a second machine of mine got the exact same issue. The expiry date on the bottle is next week, so maybe that's it? Very frustrating problem since the failures really didn't make any sense.

SEKCobra posted:The gauge has too low a resolution I guess, my curves are like <5 cm in length. I guess I developed my own technique because nothing 'standard' really works, I am using wire (solder wire) to trace the shapes and then I trace that onto paper with manual air brush pens. Can measure/scan directly after that. Also printed a helper part that hooks onto the plastic so I can try and measure some 90° distances which I might be able to reference as well.

So from what I'm hearing,unless it was storesd really crazy in a warehouse, the resin should still be workable. Big thing is to mix it with some fresher resin which should help things substantially. Also obviously shot them a message. Bought this resin 2 months ago and like a week ago so pretty stupid it was this stale. So ancy to just deal with Vulcan instead of random companies from overseas w00tmonger fucked around with this message at 06:16 on Aug 6, 2021 |

Ok, got the new wheels yesterday, went ahead and replaced 5 of the 6 for the z axis(would have done all 6 but I didnt feel like loving with removing the extruder motor, the wheel looks okay). Got something printing now to see if that solved the issue or if theres another thing im going to have to mess with and find out what the issue it.

Acid Reflux posted:I'm friendly with a couple of the guys from 3D Resin Solutions in Illinois, who are the ones doing the manufacturing for Vulcan. I didn't get in on the beta test for that one, but I've done a lot of testing for their other resins, and if Vulcan is even half as good as the rest of the stuff they make then it should be pretty nice to use. They don't have the lowest prices in the industry but I do think they make some of the best resin you can buy (at least for my purposes). I discovered their products about two years ago and have been using them almost exclusively ever since... it was a case of becoming chummy after becoming a customer, and not the reverse, but I still don't usually mention them here because I don't ever want to sound like I'm shilling for them. except maybe this one time Cool, what's better about it? Durability, detail?

went ahead and printed an xyz test cube and it came out pretty good, a bit wavey on the y side, but with my printer these test cubes have always done that. i wonder if the other prints i was trying have some issue with them

Do any of these new alternative resin vendors offer niche-y engineering/casting/mechanical resins, or just figurine modelling/‘abs-like” common offerings? i’m not wedded to siraya but i don’t think there are any alternatives to specialized stuff like Sculpt Ultra.

What digital calipers do you cats use? And what is the best price:quality one out there?

My main one is a set of Mitutoyos but they're certainly on the ritzy side -- $130 or so. They are lovely though and the difference in quality compared to a cheaper set is immediately noticeable. When I was in college and only had 30 dollars to spend, I got a set of dial calipers. You can get a good set for that price and I prefer them to cheap digital ones.

I have these and they are good. I also have some no-brand ones that are similar, any of the newer HF-tier ones are good, they seem to have solved the ‘kills battery when off in case’ problem, although taking the battery out is also easy. It’s a big jump in price to Mitotuyo pro-level gear.

Much greater bang for your buck with a vernier caliper. Plus you get more street cred.

I buy and use Neiko calipers for myself and the makerspace. A company called iGaging is the BattleBots standard for a variety of measurement devices. I just bought a dial test indicator from them with a selective magnetic base and it's pretty good.

The company that makes my printer makes resins with different properties, but they're not inexpensive. They're called B9 Creator, lots of niche stuff. People have been printing molds with the flexible resin to use for wax injection.
