What model resin you using these days?

A while back I gave butyl rubber gauntlets a try instead of disposable nitrile, on the basis that butyl is actually an effective long-term barrier to resin components and is not porous in the form-factor of a fairly stiff and heavy-walled glove, just so I could work with one pair of gloves and not generate so much PPE waste- unfortunately the butyl is very tacky and picked up way too much dust and crud from the environment + took away most of my tactile feedback and fine dexterity. There are thinner semi-disposable butyl rubber gloves you can get but they're way too expensive to replace regularly. I don't love the false security nitrile gives you, wrt still exposing your skin to some small level of sensitizers, but they seem like the best compromise once you make peace with throwing a whole lot of gloves out over the course of a work-week. Best practice, aside from changing gloves like clockwork, is to opt for the heaviest gloves you can get, the wall thickness does have a significant impact on slowing chemical penetration through to the skin. You can also wear that second-skin stuff under the gloves, as a final barrier, but I'd personally rather double up.

We found out this week that our supplier of printing model resin is going out of business (were bought out by whom they can't say). Which really sucks because they supplied a lot of resin to many manufacturers and price was fair but the biggest advantage outside of accuracy was you could steam any articulation marks/lab grime off of them. Kinda curious what others have found out there or are using that is a fair price, accurate, and could steam. Ours was $70/liter, beige color. What say you.

Elegoo resins work exceptionally well. However, I find that dental stone models work better than printed resin models.

What is the best resin material for scanning?

Rarely need to scan resin models. Most seem to scan pretty well without scan spray or powder.

if youre starting with a digital file, why do you need to scan the print? maybe i am missing something here

Occasionally the digital bites are so off I scan the correct bite after I print them, then finish designing the case. I usually just guestimate, but sometimes they are way off.

Sometimes we scan prints for diagnostic purposes, if something really weird with die fit or whatever is going on and the usual cube + town QC battery doesn't give me enough feedback. This is more for milled models, but sometimes comparing scans with Zeiss comparison software (the basic version is free!) can show you something hard to articulate in a very obvious way, like XY skewed models (ran into those once due to a faulty servicing) can be hard to identify if it happens because you're not checking the squareness of calibration cube sides with real metrology, you're just checking XYZ dimensions, but it jumps out at you when you overlay a scan over the original mesh.

Yes, I used a scan spray too, I am looking for a scannable printer resin for those occasions that require scanning a printed model.

Precision model resin from formlabs and phrozen's 8k resin scan fine.

jeez, I hope you are charging extra!
I understand, didn't think of that and we have had to take a new bite scan from time to time.

It is usually just easier for us to just print and scan the bite instead of making the patient come back to the Dr.s office for another appointment. We include the bite issue in the case notes for the doctor to see.

My favorite resin is ApplyLabWorks MSLA Sand. Prints great on our Elegoo and Phrozen printers, and scans easily if needed for resetting bites or for verification. Little to no stirring if you print daily. Best thing is it's only $40/liter with free ground shipping if you get a few bottles at a time. I have no affiliation with them, just a big fan.

Been using DMD-31 beige for the last 3 years now. Very happy with it and not had any issues with it at all. You can get 5L cans for 375 euros. Printing on Asiga Max.
