Polycarbonate is the strongest, most heat-resistant filament most Bambu owners can realistically print — and also the one most likely to crack, warp, or fog up the first attempt. This guide covers exactly how to print PC on Bambu Lab printers: which machines qualify, drying, plate prep, and the slicer settings that stop layer cracking.
PC success formula
Dry the spool, use an enclosed printer and keep cooling low. Start from the stock Bambu PC profile, run a 100–110 °C bed with glue, and preheat the chamber before large parts.
How to Print PC on Bambu Lab: Quick Settings
| Setting | Recommended (Bambu PC) |
|---|---|
| Nozzle temp | 260–280 °C |
| Bed temp | 100–110 °C, Engineering/Textured PEI + glue |
| Chamber | Enclosed, door closed — mandatory |
| Part cooling fan | 0–30% (more = layer cracking) |
| Drying | 80 °C for 8–12 h (AMS HT reaches this; AMS 2 Pro does not) |
| Nozzle | Stainless/brass OK — pure PC is not abrasive (PC-CF is: hardened steel) |
Which Bambu Printers Can Print PC?
The first rule of how to print PC on Bambu Lab machines: the printer must be enclosed and the hotend must reach 280 °C. That means X1C, X1E, P1S, P2S, X2D, H2D and H2C are all candidates; the open-frame A1 and A1 Mini are not — PC cools too fast in open air and cracks between layers. For per-printer material limits, see our X2D filament compatibility guide and best filament for P1S roundup.
Step 1: Dry the Spool at 80 °C
PC absorbs moisture aggressively, and wet PC prints hazy, bubbly and brittle. Per Bambu Lab’s filament guide, PC wants a genuinely hot dryer: around 80 °C for 8–12 hours. Note that the AMS 2 Pro caps at 65 °C — enough to keep PC dry, not enough to rescue a soaked spool; the AMS HT (85 °C) or a dedicated dryer is the right tool. Our filament dryer guide covers options, and proper storage keeps it dry between prints.
Step 2: Plate Prep Against Warping
PC pulls harder off the plate than ABS. Community consensus on how to print PC on Bambu Lab plates: Engineering Plate or Textured PEI at 100–110 °C, always with a layer of Bambu liquid glue — the glue acts as both adhesive and release layer. Add a brim (5–8 mm) on anything with a large footprint. The mechanics are the same as in our ABS anti-warping guide, just more so.
Step 3: Slicer Settings That Matter
- Start from the stock Bambu PC profile in Bambu Studio — it already handles temps and fan limits.
- Fan: keep part cooling at 0–30%. Aggressive cooling is the #1 reported cause of layer cracking in PC.
- Speed: moderate — outer walls around 50–80 mm/s give better layer bonding than full speed.
- Door closed, chamber warm: let the bed preheat the chamber 10–15 minutes for large parts.
- First layer: slower and hotter beats squished — PC adheres by heat, not pressure.
How to Print PC on Bambu Lab Without Common Defects
Even when you know how to print PC on Bambu Lab hardware, three failures dominate user reports:
- Layer cracking / delamination: chamber too cold or fan too high. Close the door, drop the fan, slow down.
- Hazy surface, bubbles, stringing: moisture. Re-dry at 80 °C — no slicer setting fixes a wet spool.
- Corner lifting: more glue, brim, and check the plate is genuinely at 100 °C+.
PC vs the Alternatives
Once you know how to print PC on Bambu Lab reliably, compare whether the extra heat resistance is truly necessary. PC beats ABS on heat (~110 °C+ vs ~100 °C) and impact strength, at the cost of printability. If your part doesn’t truly need that ceiling, ABS or ASA is the easier win — see ABS vs ASA.

FAQ
Can beginners learn how to print PC on Bambu Lab printers?
On an enclosed Bambu with the stock PC profile, a dried spool and glue on the plate — yes. Reports consistently show that drying and chamber discipline, not skill, decide how to print PC on Bambu Lab machines successfully.
Do I need a hardened nozzle for PC?
Not for pure PC — it isn’t abrasive. PC-CF and other fiber-filled blends do require hardened steel; see our nozzle comparison.
Is PC food-safe or outdoor-safe?
Neither by default: FDM surfaces harbor bacteria, and PC yellows under UV. For outdoor parts, ASA remains the community pick.
