Polycarbonate is the strongest 3D printer filament presented in this list, it is extremely durable and resistant to both physical impact and heat. PC is able to withstand temperatures of up to 110°C. With it also being transparent, this explains why it is used in commercial items such as, bullet proof glass, scuba masks, and electronic display screens.
This filament shouldn’t be confused with acrylic or plexi-glass, which shatters or cracks under stress. Unlike these two materials, PC is moderately flexible, allowing it to bend until eventually it deforms. Polycarbonate filament is hygroscopic, this is allowing it to absorb water from the air, don’t forget to store it in a cool and dry place to ensure better quality prints.

When should I use PC?
Polycarbonate is an ideal 3D printer filament for parts that need strength, toughness, and shape in high-temperature environments, also try to take advantage of its optical clarity in lighting projects.
