Taulman3D Taulman Nylon 680 - 1.75mm (1lb)

It literally says in the description that it is autoclaveable.

It is supposedly 'flash' autoclavable. Presumably that means autoclavable if the cycle is quick... There are autoclaves, such as the Statim used in dentistry, that has a 6 minute full cycle with 2.5 minutes at 137C, that might be considered 'flash' autoclaving... It does dental instruments just fine... Not sure about this 680 stuff just yet...

This FDA-certified nylon is aimed at established FDA-certified laboratories and not at all at home users or users in unrelated industries. Much of the merit in the FDA-certification of this material likely has to do with the way Taulman tracks its manufacturing processes at every stage. The FDA certification process is complex, time-consuming, expensive, and requires at least a small team of experts and auditors. The FDA certifies entire manufacturing facilities, if not specific manufacturing processes. This means you'd need to certify not only your business' manufacturing area, but also each step in the manufacturing process (test filament on receiving, test filament pre-printing, test final products, routine audits of the manufacturing facility, guidelines on how the area is maintained...) - and this is expensive (tens or hundreds of thousands of dollars). (The FDA is eager to get into it, and trying to build the hype - check out this ridiculous, official FDA video on 3d printing, and enjoy the heavy dubstep: https://www.youtube.com/watch?v=kXWKF-PzEF8 ) This filament could easily be integrated into and employed in an FDA-certified manufacturing facility, and that's the target audience. In this case, the manufacturer could indeed get a 3d printer FDA-certified. That printer would likely be used only for a specific set of materials and for a specific set of projects. Every print and material changeover would be recorded. So if you're asking about FDA certification on a forum, you should be aware... True FDA certification will absolutely never ever be given to an at-home 3D printer (like a 3d hub). [degree + 3yr in pharmaceuticals, 1yr working in 3d printing]

If it's used downstream, out of body, (like in an autoclavable suction device), a print/device may not need FDA approval... If it's upstream, for insertion in the body for any length of time, yes, it would have to go thru certification (typically expensive)...

If it's for something like a dental implant surgical guide, one time use, probably OK, but that's a guess... There are surgical guides that are printable in resin that might be a better choice and they are FDA certified for that sort of use... So far as I know...
