The Bambu Lab P2S 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. Both are enclosed CoreXY printers with a 600 mm/s rated top speed and automatic calibration. The CORE One+ costs $450 more and gets you an open-source design and 8 multicolor slots to the P2S's 4; the P2S answers with extra engineering materials (PA-CF) and 13% more build volume.
Early in release cycle — no urgency to wait
Best for: Serious makers and prosumers who need enclosed printing for ABS, ASA, PA, PA-CF, and PC — and want Bambu's plug-and-play experience at a prosumer price.

The P2S was released on Oct 14, 2025, 394 days ago. Based on Bambu Lab's release cadence, we expect the next model (P3S or next prosumer model) around late 2027 — about 323 days away, which puts the P2S 55% of the way through its cycle.
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.
Both are early enough in their cycles that timing should not decide this one. The P2S has roughly 323 days of runway on past cadence and the CORE One+ has roughly 118 days of runway on past cadence. Pick on features and price.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The P2S 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 P2S versus $67 for the CORE One+ — the P2S is both cheaper and roomier, so it wins on value outright.
If you are buying before Dec 5, 2026, the active sale tips value toward the P2S.
Our pick for most buyers is the P2S, for a lower price ($450 less) and extra engineering materials (PA-CF), plus a higher editor score (9.2 vs 9.0). Go for the CORE One+ instead if you want an open-source printer you can modify and repair yourself — the P2S is not open source. The P2S is also in a sale window right now (Bambu Black Friday 2026, until Dec 5, 2026).
How we judge timing and deals: read our methodology →
The P2S enclosure maintains a more consistent chamber temperature over the P1S, reducing warping on long ABS and PA prints.
PLA through PC — the P2S handles the entire engineering filament spectrum with reliable results.
The P-series CoreXY enclosure design strikes the best balance of price, speed, and material capability in Bambu's lineup.
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.
