The A1 (entry) and P1S (prosumer) are a step-up decision within Bambu Lab's lineup: same ecosystem, different class of machine. Note that the P1S has been replaced by the P2S and is no longer sold new. The P1S costs $250 more and gets you an enclosed chamber (with ASA, PA, PA-CF and PC on its materials list).
Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Makers who want large prints and multicolor capability without an enclosure — ideal for PLA, PETG, and flexible materials.

Best for: Makers who need an enclosed printer for ABS, ASA, PA, and PC at prosumer price — now available at clearance pricing after P2S launch.

The A1 was released on Oct 19, 2023, 1,120 days ago. Its previous release cycle ran about 365 days; it is now 755 days past that point and no successor has been announced.
The P1S has been replaced by the P2S and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
On timing alone, the A1 is the safer buy right now — it is 755 days past its ~365-day cycle with no successor announced, while the P1S has already been replaced by the P2S.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The A1 lists at $299 and the P1S at $549 — $250 apart, so the P1S costs 84% more.
Per litre of build volume, that works out to $18 for the A1 versus $33 for the P1S — the A1 is the better value per litre as well.
Buy the A1. The P1S has already been replaced by the P2S and is no longer sold new, so it is only worth considering at a clearance price. If the P1S appealed to you, the fair comparison today is the A1 against the P2S.

The A1 Combo includes the AMS Lite for 4-color filament switching — the same system used on the A1 Mini and A2L.
Roughly 2.9 times the volume of the A1 Mini — great for terrain, cosplay props, and functional parts. The A2L is the step up if you need a larger bed-slinger.
Works with Bambu Studio, Bambu Handy app, and the full Bambu filament ecosystem including multi-material profiles.
Active chamber temperature control enables reliable ABS, ASA, PA, and PC printing without warping.
500 mm/s print speed with Bambu's vibration compensation delivers fast, accurate prints.
With the P2S released, P1S prices are at their lowest — an opportunity for budget-conscious buyers.
