Bambu Lab P2S
4.9Choose the P2S if you print ABS, ASA or composite filaments and need an enclosed, filtered chamber with a 256 mm cube build volume.
Pros
- Enclosed chamber holds heat for ABS and ASA and filters fumes through carbon.
- 256 mm cube build volume fits large parts the A1 mini cannot.
- Hardened-steel nozzle and 300°C hotend handle engineering and reinforced filaments.
- AI monitoring catches spaghetti and nozzle failures; 1080p camera with lighting.
- Reviewers call prints clean and near problem-free with little calibration.
Cons
- No current store price listed, so the real cost is unclear.
- Takes up a lot of desk space, per reviewers.

Questions and answers
- Can the A1 mini print ABS or ASA?
- Not well. It has no enclosure, so the part cools unevenly and warps. The P2S is the one built for ABS and ASA, with an enclosed chamber and carbon filtration.
- Is the P2S worth the extra money over the A1 mini?
- Only if you need its enclosure, 256 mm cube volume, or engineering filaments. For PLA and PETG on a desk, the A1 mini at $199.00 covers most of it for far less.
- Which is better for a beginner?
- The A1 mini. Reviewers call it easy to set up with full-auto calibration. The P2S is also praised as easy to learn, but it costs more and takes up much more space.
- Which prints faster?
- The P2S has the edge on speed and stability thanks to CoreXY motion and a servo extruder with about 8.5 kg of force. The A1 mini is still described as fast for its class.
- Do both support multi-color printing?
- Yes. The P2S offers an AMS combo, and the A1 mini uses AMS lite for four colors.
- Which is quieter?
- The A1 mini is rated under 48 dB in silent mode. The P2S is described as quiet by reviewers, but its enclosed chamber and fans add noise.
