Polycarbonate (PC) filament for heat-resistant parts
Part of the heat-resistant filament guide. Polycarbonate and PC blends have some of the higher heat-deflection values among common filaments, which makes them a candidate for enclosures near heat sources, lamp housings and motor mounts. They need high nozzle and bed temperatures and an enclosed printer. Nothing here was printed or measured by this site; every value links to its source.
What Bambu says about printing it
| Category | In Bambu's table? | Bambu Lab A1 mini | Bambu Lab A1 | Bambu Lab P1S | Bambu Lab X1 Carbon (X1C) | AMS | AMS lite |
|---|---|---|---|---|---|---|---|
| PC | Yes | Not Recommended | Not Recommended | Recommended | Recommended | Compatible | Compatible |
| PC-CF/GF | No (derived, see note) | Not rated (Bambu recommends an enclosed printer) | Not rated (Bambu recommends an enclosed printer) | Recommended (Bambu printer-requirements table) | Recommended (Bambu printer-requirements table) | Not rated by Bambu | Not rated by Bambu |
- PC-CF/GF: Not a row in Bambu's compatibility table. Bambu's printer-requirements table groups ABS, ASA, PC, PA "and their CF/GF reinforced materials" under enclosed printers, and its nozzle guidance requires a hardened steel nozzle for CF/GF materials. Bambu names PC-CF in that group. (source)
| Material group | Hardened steel nozzle | Nozzle temp (°C) | Bed temp (°C) | Drying before use |
|---|---|---|---|---|
| PC | Not required | 260–290 | 100–120 | Required: 80 °C for 8 h (oven) |
- PC: PC-CF is named in Bambu's enclosed-printer group; CF variants need a hardened nozzle per Bambu's CF/GF guidance. (source)
Heat-resistance values from manufacturer datasheets
Sorted by HDT at 0.45 MPa. A dash means the datasheet does not give that value (or gives it without a stated load), so it is left blank rather than estimated. HDT is a lab comparison value measured on test bars under a fixed load, not a rated service temperature, and depends on test method, print orientation and annealing. Retrieved .
