The Bambu Lab P1S (prosumer) and Prusa Research CORE One L+ (professional) 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 Note that the P1S has been replaced by the P2S and is no longer sold new. Both are enclosed CoreXY printers with a 500 mm/s rated top speed and automatic calibration. The CORE One L+ costs $1,450 more and gets you 77% more build volume and an open-source design; the P1S answers with 4-slot multicolor.
This printer is no longer sold new. It has been replaced by the Bambu Lab P2S.

The P1S has been replaced by the P2S and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.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 L+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 279 days, so it is 33% of the way through — roughly 188 days before a successor would be due at that pace.
On timing alone, the CORE One L+ is the safer buy right now — it is only 33% of the way through its expected cycle, while the P1S has already been replaced by the P2S.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 L+ at $1,999 — $1,450 apart, so the CORE One L+ costs 264% more.
Per litre of build volume, that works out to $33 for the P1S versus $67 for the CORE One L+ — the P1S is the better value per litre as well.
Buy the CORE One L+. The P1S has already been replaced by the P2S and is no longer sold new, so it is only worth considering at a clearance price.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 L+ against the P2S.
