The Anycubic Kobra S1 Max (professional) and Bambu Lab P1S (prosumer) 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 Note that the P1S has been replaced by the P2S and is no longer sold new.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 Kobra S1 Max costs $250 more and gets you 156% more build volume and support for PLA-CF, PETG-CF and PVA.
First-generation product — recently released, still early days
Best for: Professional makers and small studios who need large-format enclosed printing for engineering filaments at a competitive price — and want Anycubic's ecosystem over Creality or Qidi alternatives.

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 Kobra S1 Max was released on Nov 25, 2025, 352 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
The P1S has been replaced by the P2S and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
On timing alone, the Kobra S1 Max is the safer buy right now — it launched only 352 days ago, while the P1S has already been replaced by the P2S.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 Kobra S1 Max at $799 — $250 apart, so the Kobra S1 Max costs 46% more.
Per litre of build volume, that works out to $19 for the Kobra S1 Max versus $33 for the P1S — so the pricier Kobra S1 Max actually gives you more build space per dollar.
Buy the Kobra S1 Max. The P1S has already been replaced by the P2S and is no longer sold new, so it is only worth considering at a clearance price.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 Kobra S1 Max against the P2S.

One of the largest enclosed build volumes in the prosumer/professional tier — suited for large engineering parts, architectural models, and batch production.
Maintaining 65°C across a 350×350 mm chamber is a meaningful technical achievement — ensuring consistent results for ABS, ASA, and PA across the full build plate.
The S1 Max extends the Kobra ecosystem into the large-format enclosed segment, enabling Anycubic users to scale up without switching brands.
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.
