Are any 3D printed materials skin safe?

Just saw a supplier for bio-compatible resins on a website in the 3D printer section. They are listed as "new" and no prices are given and details are not given. On another website the information about bio-compatible resins says the limits are 30 days against the skin or 24 hours against a mucous membrane.

Just makes sure you are not using any urethane products. Silicone or nylon should be ok. Acrylic is not flexible enough and has some nasty compounds in it.

the MSDS sheets are nothing but scary but have not been able to find sheets for all the resins used by SLA 3D printers! The SLA printers make a good surface that would be easy to polish if it needs it.

If you're going to be 3D printing a device, just check to see exactly what's in the printing material. I would assume anything nylon or acrylic should be fine for skin contact. The one question I'd have is whether the surface comes out smooth enough to be comfortable.

Ever since looking at the HOPE foreskin restoration device I have been thinking about 3D printers and what I might do with one. Just a couple minutes ago I searched thingiverse.com for circumcision to see what would popup. Glad to see a foreballs "mock up" and got to thinking... would that even be safe? FYI a search for foreskin shows a few devices.
