Polycarbonate filament, also known as PC, is a little more tricky to print than some more common filaments, but the payoff is a super strong 3D printed part with a greater impact strength than ABS. Polycarbonate should be printed with an enclosed 3D printer that has a print bed capable of reaching at least 90c. 100-110 is preferable for some brands of Polycarbonate filament, so be sure to check the settings recommended for your particular filament.Polycarbonate is a highly hygroscopic material a …

Here is what MakerGear says:"Once a new nozzle has been installed onto a barrel, do not install that same nozzle onto a different barrel or leakage may occur. As you install a new nozzle onto a barrel, a small amount of material is removed from the nozzle to create a custom fit. This makes the nozzle incompatible wit …
