Overview
Polycarbonate (PC) is one of the strongest FDM materials available - it is the material used in bulletproof glass and safety helmets. It combines outstanding impact resistance with a high heat deflection temperature, making it suitable for structural components in demanding environments.

Applications
Structural bracketsProtective shieldsHigh-heat enclosuresLens housingsRiot & safety equipmentAerospace test parts
Printing Tips
Print PC at 270–310 °C on a bed at 110–130 °C. A fully enclosed, heated chamber printer is required. Use polycarbonate-specific bed adhesives. First layer speed should not exceed 15 mm/s.
Frequently Asked Questions
Is polycarbonate food-safe?
Standard PC is not certified food-safe for long-term food contact due to potential BPA traces and the porous nature of FDM prints. Contact us for food-safe certified alternatives.
