Bambu Lab A1 Mini vs Bambu Lab P1S
The A1 Mini (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 Note that the P1S has been replaced by the P2S and is no longer sold new.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 $330 more and gets you an enclosed chamber (with ABS, ASA, PA, PA-CF and PC on its materials list) and 188% more build volume.

Timing: When to Buy
The A1 Mini 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The P1S has been replaced by the P2S and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.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 Mini 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the safer buy right now — it is 755 days past its ~365-day cycle with no successor announced, while the P1S has already been replaced by the P2S.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 →
Deals & Pricing
The A1 Mini lists at $219 and the P1S at $549 — $330 apart, so the P1S costs 151% more.
Per litre of build volume, that works out to $38 for the A1 Mini versus $33 for the P1S — so the pricier P1S actually gives you more build space per dollar.
- A1 Mini: On sale until Dec 1, 2026. Bambu Black Friday 2026 — Bambu's sale runs from October 27 to December 1. The best annual sale event for Bambu printers.
- P1S: No longer sold new, so there is no sale calendar to track — judge any listing against the P2S's $549 list price.
Who Should Choose Each
Choose the Bambu Lab A1 Mini if…
- you want our higher-rated printer — 9.0 vs 8.6 out of 10
- you want to spend less — it is $330 cheaper ($219 vs $549)
- you are buying now — it is the safer pick on timing (overdue for refresh, vs superseded for the P1S)
- your prints fit within 180 × 180 × 180 mm — then the P1S's extra build volume is money you do not need to spend
- you are buying before Dec 1, 2026 — it is in Bambu Black Friday 2026 right now
Choose the Bambu Lab P1S if…
- you find it at a clearance price — it is no longer sold new, and the P2S is its replacement
- you want to print ABS, ASA, PA, PA-CF and PC — it is enclosed and lists them, while the A1 Mini is open-frame
- you print large parts — its 256 × 256 × 256 mm build volume holds 188% more than the A1 Mini's 180 × 180 × 180 mm
Our Take
Buy the A1 Mini. The P1S has already been replaced by the P2S and is no longer sold new, so it is only worth considering at a clearance price.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 Mini against the P2S.
