Biomakespace have been testing some PP 3D prints in our autoclave with some success, there was no difference in integrity up to about 8 cycles (before someone emptied the autoclave without realising the test piece was in there and threw it away!)
-- There was an increase in what I can only describe as "tackiness" of the material though so you'd want to test that there isn't leaching from the outer layers that could mess with your assay.
We didn't have too much trouble printing with it using our Prusa i3 MK3 and we're planning a more thorough experiment with some tests for strength and deformity. I can find out the filament brand and printer settings from the member who was using it if that helps!

Making custom modification pieces to standard lab-ware to make certain assays easier to run. Basically devices that come into contact with molten agar. PP looks pretty finicky to print with. Polycarbonate looks easier to work with but will breakdown over repeated cycles and looks sensitive to pH swings? We had someone print a mold and try to cast resin in it but the resin wasn't getting into all the nooks and crannies of the mold even with degassing it under vacuum. Thank you for the suggestions will read more into PP as I trust the material, just finding the best printer for it I suppose.

It may be easier to mill or machine polypropylene and polycarbonate. Polypropylene can withstand autoclaving but are difficult to 3D print. Polycarbonate can also withstand autoclaving and is easier to 3D print.--On Fri, Apr 26, 2019 at 6:29 PM Dakota Hamill <dko...@gmail.com> wrote:Has anyone had any success with either heated extrusion or resin printers to create prints with resins capable of standing repeated autoclave cycles?--
