The Bambu Lab P1S and Prusa Research CORE One+ are both prosumer-tier printers, but the CORE One+ costs 1.8× as much — so the question is what the extra money buys. Note that the P1S has been replaced by the P2S and is no longer sold new. Both are enclosed CoreXY printers with automatic calibration. The CORE One+ costs $450 more and gets you an open-source design and a top speed of 600 mm/s (vs 500); the P1S answers with extra engineering materials (PA-CF) and 13% more build volume.
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 It has been replaced by the Bambu Lab P2S.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.

The P1S has been replaced by the P2S and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.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 CORE One+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 209 days, so it is 44% of the way through — roughly 118 days before a successor would be due at that pace.
On timing alone, the CORE One+ is the safer buy right now — it is only 44% of the way through its expected cycle, while the P1S has already been replaced by the P2S.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The P1S lists at $549 and the CORE One+ at $999 — $450 apart, so the CORE One+ costs 82% more.
Per litre of build volume, that works out to $33 for the P1S versus $67 for the CORE One+ — the P1S is both cheaper and roomier, so it wins on value outright.
Buy the CORE One+. The P1S has already been replaced by the P2S and is no longer sold new, so it is only worth considering at a clearance price.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 CORE One+ against the P2S.

How we judge timing and deals: read our methodology →
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.
The CORE One+ matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.
Unlike Bambu's closed ecosystem, every component of the CORE One+ can be modified, repaired, or community-improved.
The CORE One+ (Gen 2) can be ordered with Prusa's INDX toolchanger in 4- or 8-tool versions, shipping from 15 October 2026. Each material gets its own nozzle, with about 12 seconds per material change and almost no purge waste. The MMU3 remains compatible as a 5-color add-on.
