Polycarbonate sheets can be bent cold without cracking, so it should not be brittle, quite the opposite.
I know that PET is brittle if it is printed with absorbed moisture, it needs to be dry, perhaps PC is the same.
Interesting! I have a feeling that PC is more flexible with absorbed moisture, like nylon. But I did not check it for sure.
EDIT: I dry PC before printing, and print

... seems to be "pure" PC, without additives for adjusting physical and longterm behaviour ...
Do you suggest that what I see is normal for a virgin polycarbonate, and that polycarbonate with additives would be better?
I have been looking at polycarbonates with additives, they normally print at low temperatures (240-260C), which suggests that they are not very heat resistant...

Hi, I am looking for an advice about polycarbonate, which seems strangely brittle.
I *think* I know how to print PC, at least I can get strong and dimensionally accurate results, at least initially. But the parts which I used for my printer (e.g. hotend mount, bed mounts) crack with time, see my photo.
If in use long enough, they just fall apart along the crack lines. I replace what I can with

Hi! I am looking for a mount for water cooled chimera. It is attached from the rear on four m3 bolts:
I did not find an existing mount. I could design one in cad, but I am not sure what it should look like. What would be my options?
