Interesting. Unfortunately they don't say what the polycarbonate is blended with in all their literature. Not that it really matters as long as it works; I was just curious.Hello Everyone,
While I can't personally speak to the performance of the material. The model supplier indicates he has not had any issues.
The material is not a pure PolyCarbonate but a special blend for 3D printing.
If your interested the material datasheets are linked at the bottom of the supplier page. Here: Prusament PC Blend Jet Black 1kg - Prusa Research - https://shop.prusa3d.com/en/prusament/1252-prusament-pc-blend-jet-black-1kg.html
I'd even go so far as to say that if the gear fails under normal conditions I'd be happy to replace it with the same again for free. Excluding shipping of course. If they do fail I might even be open to replacing them with nylon. I would ask that the original be returned or a discussion with photos etc. for study.
We still need to know which shaft type is being printed. There are two that were used. Can you let us know? Thanks.
Not the greatest photo but here are the two types side by side.
