Bambu Lab A1 vs P1S

How the two machines differ on paper: build volume, process, enclosure, nozzle temperature, launch year and the materials each manufacturer names. This is a specification comparison, not a hands-on test.

Key differences

  • Both list the same nominal build envelope: 256 × 256 × 256 mm.
  • Bambu Lab P1S is enclosed; Bambu Lab A1 is an open-frame design.
  • Both list a maximum nozzle temperature of 300 °C.
  • Both were introduced in 2023.
  • Material lists differ: Bambu Lab P1S documentation also names PET, ABS, ASA, Nylon / polyamide, Polycarbonate blends. A material missing from a list means it isn't documented there, not that it can't print.
  • Detailed specifications that differ: toolhead acceleration max (10000 mm/s² vs 20000 mm/s²); machine dimensions (465 × 410 × 430 mm vs 389 × 389 × 458 mm); machine weight (8.3 kg vs 12.95 kg); monitoring camera (Low frame rate; up to 1080p vs 1280 × 720 at 0.5 fps).
  • Only the Bambu Lab A1 profile documents filament sensors (Runout, Odometry, Tangle), power loss recovery (Supported).
  • Only the Bambu Lab P1S profile documents air filter (Activated carbon), input power (100–240 VAC, 50/60 Hz; rated 1000 W at 220 V or 350 W at 110 V).

Before you choose

Published specifications don't settle print quality, reliability or noise. Compare the exact configuration, bundled accessories, regional price and support with each manufacturer, and check that the materials you need are supported on the configuration you'd buy.

Bambu Lab

Bambu Lab A1

Filament printer with a 256 mm cubic build volume.

The specification table identifies PLA, PETG, TPU and PVA as ideal materials. ABS, ASA, PC, PA, PET and fiber-reinforced polymers are explicitly not recommended; the nozzle temperature alone does not establish material suitability.

Bambu Lab

Bambu Lab P1S

Enclosed filament printer with a 256 mm nominal cubic build volume.

The P1S specification lists a plastic-and-glass enclosure, an auxiliary part-cooling fan, a chamber-regulator fan and a control-board fan. These distinguish its configuration from the open-frame P1P shown in the same comparison.
