The Bambu Lab P1S (prosumer) and Prusa Research Mini+ (entry) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. Note that the P1S has been replaced by the P2S and is no longer sold new. The P1S costs $90 more and gets you an enclosed chamber (with ABS, PA, PA-CF and PC on its materials list) and 188% more build volume; the Mini+ answers with an open-source design.
This printer is no longer sold new. It has been replaced by the Bambu Lab P2S.
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.

Best for: Beginners who prioritize open-source hardware, community support, and long-term reliability over speed — and don't mind a slower, more deliberate printing experience.

The P1S has been replaced by the P2S and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
The Mini+ was released on Apr 25, 2021, 2,027 days ago. Its previous release cycle ran about 730 days; it is now 1,297 days past that point and no successor has been announced.
On timing alone, the Mini+ is the safer buy right now — it is 1,297 days past its ~730-day cycle with no successor announced, while the P1S has already been replaced by the P2S.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 Mini+ lists at $459 and the P1S at $549 — $90 apart, so the P1S costs 20% more.
Per litre of build volume, that works out to $33 for the P1S versus $79 for the Mini+ — so the pricier P1S actually gives you more build space per dollar.
Buy the 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 The P1S has already been replaced by the P2S and is no longer sold new, so it is only worth considering at a clearance price.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 Mini+ against the P2S.
