Best Filament for the Bambu Lab P1P
The open-frame CoreXY that put fast, hands-off printing within reach. Best at PLA and PETG out of the box.
Last updated: June 2026
The P1P is the open-frame member of the P1 family: the same 256 mm CoreXY motion system and 500 mm/s ceiling as the P1S, but without side panels or a top lid. Bambu stopped manufacturing it in February 2026, though spare-parts support runs to 2031, so there's a large installed base still printing daily. Out of the box it's a PLA and PETG machine, since the lack of an enclosure means the chamber never warms up, which matters the moment you reach for higher-temp materials.
What the Bambu Lab P1P prints well
Recommended materials for this printer:
No enclosure, so ABS, ASA, PC and nylon will warp and crack. Stick to PLA, PLA+, PETG and TPU for reliable prints. Carbon- and glass-fibre composites also need a hardened nozzle first.
Filament choice on a stock P1P is mostly about what tolerates an ambient chamber. PLA, PLA+, PETG and TPU all run fine, and the direct-drive extruder handles flexibles down to ~95A without trouble. ABS, ASA, PC and nylon technically fit the 300°C hotend but warp and delaminate badly in open air, so add the official enclosure kit before committing to them. The stock 0.4 mm nozzle is stainless and will be chewed up by carbon- or glass-filled filament; swap to a hardened nozzle first.
Bambu Lab P1P specs that affect filament
This one's for someone who prints mostly PLA/PETG for models, prototypes and functional parts in a room they don't mind venting, and who wants the lowest-cost path into Bambu's ecosystem. If your roadmap includes ABS, ASA or engineering composites, budget for the enclosure upgrade up front, or look at the P1S, which bakes it in.
Filament notes for the Bambu Lab P1P
- Stock open frame: PLA, PLA+, PETG and TPU are the sweet spot, with no enclosure needed and no warping headaches.
- ABS, ASA, PC and nylon need the enclosure upgrade kit to avoid warping and layer cracking; a bare P1P will fail these.
- The direct-drive extruder pulls flexibles (TPU ~95A) reliably. Keep speeds moderate and the spool path short.
- The 0.4 mm stainless stock nozzle is not for abrasives, so install a hardened nozzle before any CF/GF filament.
- No dryer in the base unit, so keep PETG, nylon and TPU in a dry box; wet filament shows up as stringing and pops.
- Add an AMS or AMS 2 Pro for multicolour. The AMS 2 Pro's active drying makes hygroscopic materials far more forgiving.
