PC Print Settings
Expert-recommended PC (PC) settings for all Bambu Lab printers
Why use PC?
- Highest impact resistance of any common 3D printing material
- Heat resistance up to 130°C — suitable for near-engine applications
- Optically clear when printed correctly — light transmission applications
- Excellent electrical insulation properties
- Used in professional/industrial applications (safety equipment, lenses)
- Self-extinguishing flame resistance in PC FR variant
What are the best PC print settings?
Use default Bambu Lab temperature profiles for PC. Recommended outer wall speed is 120 mm/s.
| Setting | Value | Note |
|---|---|---|
| speed.layers.outerWall | 120 | Slow for PC quality and warping control |
| speed.layers.innerWall | 200 | Moderate inner wall speed |
| speed.layers.sparseInfill | 300 | Reduced speed for high-temp PC |
| speed.initial.layer | 25 | Very slow first layer for PC adhesion |
| speed.initial.infill | 50 | Slow initial infill |
| support.advanced.topZDistance | 0.25 | Larger Z gap — PC bonds aggressively to supports |
| others.bed.brimType | Outer and inner brim | Essential — PC warps heavily |
| others.bed.brimWidth | 10 | Maximum brim width for warping control |
| quality.precision.elephantFootCompensation | 0.25 | High bed temp squish compensation |
| strength.walls.wallLoops | 3 | Extra walls for PC impact resistance |
| strength.infill.density | 25 | Higher infill for structural PC parts |
| support.thresholdAngle | 25 | PC needs support at lower overhang angles |
| quality.advanced.avoidCrossingWall | true | Reduces stringing on PC |
What nozzle size should I use for PC?
0.4mm nozzle — PC is challenging at fine resolution
0.4mm standard nozzle
0.6mm for faster PC prints with less warping
How do I dry PC filament?
Dry PC at 80°C for 8-12 hours. Critical — moisture causes bubbling and weak layers
What support material should I use with PC?
Recommended: PC base + tree supports with increased Z gap
Base: Same as model (PC) | Interface:
PC as both base and interface — no compatible dissolvable support exists for PC temperatures. Use tree supports with 0.25mm Z gap to ease removal.
Expert Tips for PC
- PC requires the HIGHEST printing temperatures (270-300°C) — H2D handles this, A1 cannot.
- Enclosed printer is ABSOLUTELY MANDATORY for PC.
- PC is the most warp-prone material — use maximum brim, consider a raft.
- Dry at 80°C for 8-12 hours. PC absorbs moisture readily.
- For clear/translucent PC, print at higher temperature with slower speed.
Which Bambu Lab printers work with PC?
Use with caution on: P1P, A1, A1 Mini, Ender 3 V3 SE, Ender 3 V3 KE, Ender 3 S1 Pro, J1
Alternatives to PC
If you can accept lower heat/impact resistance in exchange for dramatically easier printing
Trade-offs: Lower heat resistance (~80°C vs ~130°C). Lower impact resistance. Not optically clear
If you need high heat resistance but at lower cost and easier printing than PC
Trade-offs: Lower impact resistance than PC. Not transparent. Still needs enclosure
