The Bambu Lab P1S (prosumer) and Creality K2 Plus (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 Note that the P1S has been replaced by the P2S and is no longer sold new.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 4-slot multicolor and automatic calibration. The K2 Plus costs $650 more and gets you 156% more build volume and a top speed of 600 mm/s (vs 500); the P1S answers with extra engineering materials (PC).
This printer is no longer sold new. It has been replaced by the Bambu Lab P2S.

Best for: Professionals and studios who need large-format enclosed multicolor printing without the premium price of Bambu's or Prusa's flagship offerings.

The P1S has been replaced by the P2S and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.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 K2 Plus was released on Sep 15, 2024, 788 days ago. Its previous release cycle ran about 450 days; it is now 338 days past that point and no successor has been announced.
On timing alone, the K2 Plus is the safer buy right now — it is 338 days past its ~450-day cycle with no successor announced, while the P1S has already been replaced by the P2S.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 P1S lists at $549 and the K2 Plus at $1,199 — $650 apart, so the K2 Plus costs 118% more.
Per litre of build volume, that works out to $33 for the P1S versus $28 for the K2 Plus — so the pricier K2 Plus actually gives you more build space per dollar.
Buy the K2 Plus. The P1S has already been replaced by the P2S and is no longer sold new, so it is only worth considering at a clearance price.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 K2 Plus against the P2S.
