Best Filament for the Bambu Lab P2S

The reengineered P1S successor: hardened quick-swap nozzle, servo extruder and adaptive airflow, abrasive-ready out of the box.

Last updated: June 2026

The P2S launched in late 2025 as a ground-up rework of the P1S, pulling tech down from the H2 series. It keeps the same enclosed 256 mm CoreXY footprint, but the guts changed: a servo extruder that pushes up to 8.5 kg of force (about 70% more than before) and samples position and resistance to catch grinding and clogs in real time. It also ships with a hardened steel quick-swap nozzle, roughly a 30-second change between 0.4 and 0.6 mm, so it's abrasive-ready without a parts run.

What the Bambu Lab P2S prints well

Recommended materials for this printer:

PLA PLA+ PETG TPU PLA-CF PETG-CF ABS ASA PC Nylon CF / GF composites

Enclosed and abrasive-ready out of the box, so it handles the full range from PLA to engineering composites, no nozzle swap needed.

For filament, the big shift from the P1S is the stock hardened nozzle and the adaptive airflow system. The airflow can pull cool outside air for PLA and PETG or recirculate to hold heat for warp-prone ABS, ASA, PC and nylon, so it's a passive chamber, but a managed one. CF and GF composites (PLA-CF, PETG-CF, PA-CF, PC-CF, GF blends) run on the stock nozzle, the main practical win over earlier P-series. There's still no active chamber heater, so the largest engineering parts want recirculation mode and a hot bed.

AMS 2 Pro / AMS HT (up to 20 colours)

This is the pick for someone who wants the P-series form factor but prints a serious mix (flexibles, abrasive composites and engineering plastics) without nozzle swaps or warp-fighting. With the AMS 2 Pro it scales to 20 colours, and AMS HT support means high-temp materials get proper drying. Choosing today between this and the P1S, the P2S is the forward buy.

Filament notes for the Bambu Lab P2S

  • Ships with a hardened steel 0.4 mm nozzle, so it runs PLA-CF, PETG-CF, PA-CF, PC-CF and GF blends out of the box, no nozzle swap needed.
  • The quick-swap nozzle (~30 s) lets you jump between 0.4 and 0.6 mm, handy for fine multicolour PLA vs faster functional PETG/CF prints.
  • Adaptive airflow pulls outside air to cool PLA and PETG, and recirculates to retain heat for ABS, ASA, PC and nylon.
  • The servo extruder (up to 8.5 kg force) handles stiff composites and flexibles, and flags grinding/clogs mid-print.
  • Enclosed but with no active chamber heater, so for big ABS/PC parts use recirculation mode plus a hot bed and reduced part cooling.
  • The AMS 2 Pro adds active drying; pair AMS HT units for high-temp nylon and PC that need to stay bone-dry.

Frequently Asked Questions

Does the P2S need a nozzle upgrade for carbon-fibre filament?
No. Unlike the P1S, the P2S ships with a hardened steel 0.4 mm nozzle, so PLA-CF, PETG-CF, PA-CF, PC-CF and glass-fibre blends run out of the box without grinding the nozzle. The quick-swap design also makes going to a 0.6 mm for faster composite prints a 30-second job.
How is the P2S better than the P1S for filament?
Three things: the stock hardened nozzle (abrasive-ready), the servo extruder with 8.5 kg force and live clog/grind detection, and adaptive airflow that tunes cooling per material. The enclosed build volume and 300°C hotend are the same, but the P2S handles composites and engineering plastics with less setup.
Can the P2S print ABS, ASA and nylon?
Yes. The enclosure plus adaptive airflow's heat-recirculation mode holds chamber warmth for ABS, ASA, PC and nylon. There's no active chamber heater, so for very large parts you'll still close it up, raise the bed temp and cut part cooling, but day-to-day these materials run well.
How many colours does the P2S support?
Up to 20. It connects multiple AMS units, and the AMS 2 Pro adds active drying while AMS HT units target high-temp materials that need to stay dry, like nylon and PC.
