The Bambu Lab P1S (prosumer) and Prusa Research XL+ (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 Note that the P1S has been replaced by the P2S and is no longer sold new.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 CoreXY printers with a 500 mm/s rated top speed and automatic calibration. The XL+ costs $1,750 more and gets you 178% more build volume and an open-source design; the P1S answers with an enclosed chamber.
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 It has been replaced by the Bambu Lab P2S.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The P1S has been replaced by the P2S and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.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 XL+ was released on Aug 13, 2026, 91 days ago. Prusa Research has already announced what comes next: XL Pick & Place Toolhead (Late 2026). Because Prusa Research sells upgrade kits for this line, owners can move up without replacing the whole printer.
On timing alone, the XL+ is the safer buy right now — it has its next step announced (XL Pick & Place Toolhead, Late 2026), with upgrade kits for existing owners, while the P1S has already been replaced by the P2S.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 XL+ at $2,299 — $1,750 apart, so the XL+ costs 319% more.
Per litre of build volume, that works out to $33 for the P1S versus $49 for the XL+ — the P1S is the better value per litre as well.
Buy the XL+. The P1S has already been replaced by the P2S and is no longer sold new, so it is only worth considering at a clearance price.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 XL+ 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.
Unlike filament-switching AMS/MMU systems, the XL physically swaps print heads. Each material has its own nozzle, eliminating purge towers entirely and enabling true multi-material prints.
One of the largest build volumes available in a CoreXY printer at this price point — suited for large props, architectural models, and batch production.
Every component is documented, parts are stocked for years, and the community has developed hundreds of modifications and improvements.
