Bambu Lab A1 with AMS Lite vs Bambu Lab P1S with AMS
Buy the A1 with AMS Lite for PLA, PETG and TPU work in an open room, where its 500 mm/s toolhead and 10000 mm/s² acceleration are easy to live with. Buy the P1S with AMS if you print ABS or ASA, since its enclosed frame holds heat and keeps fumes and drafts out. Prices move a lot: the A1 combo ranged from $305.00 to $332.41 between October 28 and October 30, 2026, while the P1S listing showed $11.36 to $349.00 in the same window, so check the current store price before ordering.

Questions and answers
- Which is better for ABS and ASA?
- The P1S. Its enclosed frame traps heat and blocks drafts, which is what ABS and ASA need to avoid warping. The A1 is open and Bambu Lab lists PLA, PETG, TPU and PVA as its ideal materials.
- Is the A1 faster than the P1S?
- On paper yes. The A1 lists a 500 mm/s toolhead and 10000 mm/s² acceleration. The P1S listing does not state speed figures, so compare real print times for your models rather than trusting the headline number.
- Do they print the same size?
- Yes. Both have a 256 x 256 x 256 mm build volume, so a model that fits one fits the other. The choice comes down to materials and enclosure, not size.
- Is the P1S worth the extra over the A1?
- Only if you print ABS or ASA or want the built-in camera. For PLA and PETG the A1 does the job, and its recent prices of $305.00 to $332.41 were well below the P1S high of $349.00.
- Which needs less setup?
- The P1S, which Bambu Lab says is ready in about 15 minutes. A1 reviewers found it easy to assemble once running, but one reported calibration errors after a software update.
- Which has better sensors?
- The A1 lists filament runout, tangle and odometry sensors plus power-loss recovery. The P1S listing does not detail these, so check the spec sheet before relying on them.
