Polycarbonate (PC) is an extremely strong, impact resistant thermoplastic, and heat resistant. 3D parts printed with PC are accurate, strong and durable. PC filament type has the second highest tensile strength among all FDM materials. The material is also biocompatible and can be sterilizable that is why it is so extremely popular for prototyping, functional testing, tooling, and composite work. The material should be extruded at or above 300°C and high heat deflection temperature is 138°C.
