PC Applications
- Enclosures – Electronics and equipment housings
- Mechanical Parts – Gears, brackets, and structural components
- Protective Equipment – Guards and covers
- Load-Bearing Parts – Structural applications
- High-Temp Applications – Heat-exposed components
- Functional Prototypes – Engineering-grade testing
Printing Tips
- Use an enclosure – PC is warp-prone; stable chamber temperature helps prevent cracking.
- Dry before printing – Moisture can cause bubbles and weak layers. Store with desiccant.
- Use glue on the bed – Improves first-layer hold on high-temp plates.
- Expect LIDAR limitations on transparent PC – Transparent materials may affect some calibration features.

Bambu Lab PC FAQ
Q: Why does PC need an enclosure?
A: Polycarbonate is highly prone to warping due to thermal stress during cooling. An enclosure maintains stable chamber temperature, preventing warping and improving layer adhesion.
Q: Is PC safe to print indoors?
A: PC emits fumes during printing. Use proper ventilation or an enclosed printer with filtration. The enclosed Bambu Lab printers (P1S, X1C) are well-suited for PC printing.
Q: How does PC compare to PC FR?
A: Standard PC offers excellent strength and heat resistance. PC FR (flame retardant) adds UL 94 V-0 certification for applications requiring fire safety compliance.
Q: Can I print PC on an open-frame printer?
A: It’s possible, but not recommended. PC typically needs an enclosure and a high-temperature bed to avoid warping and layer cracking.
