What is polycarbonate (PC) filament?
Polycarbonate (PC) is the strongest common filament. Extremely tough, transparent, heat-resistant to ~130 °C. Demanding to print - high temperatures, enclosure required.
When to choose PC
When strength is priority #1: safety glasses, protective covers, bumpers, cosplay props that can't break. PC is the plastic choice for bulletproof glass.
Printing parameters
- Nozzle: 270-310 °C
- Bed: 100-130 °C
- Enclosure: REQUIRED, heated
- Cooling: 0-20 %
- Speed: slow, 30-50 mm/s
Challenges
PC is hygroscopic like Nylon - must be dried. Needs heated enclosure (ideally 60+ °C), otherwise warping. Difficult on desktop printers.
