Documented specifications
Bambu Lab P1S
An enclosed CoreXY filament printer with a 256 × 256 × 256 mm build volume.
In short The Bambu Lab P1S is an enclosed filament (FDM) 3D printer with a 256 × 256 × 256 mm (10.1 × 10.1 × 10.1 in) build volume. Bambu Lab claims a 500 mm/s top speed, a 300 °C (572 °F) nozzle and a 100 °C (212 °F) bed; the printer measures 389 × 389 × 458 mm (15.3 × 15.3 × 18 in) and weighs 13 kg (28.5 lb).
Documentary analysis · Not personally tested
FDM · EnclosedWhy consider it?
The same nominal volume as the A1, with an enclosure and a different motion system.
What to verify
Check the precise AMS version, adapters and accessories included. Enclosure alone does not establish material suitability.

How much space does it need?
The Bambu Lab P1S measures 389 × 389 × 458 mm (15.3 × 15.3 × 18 in) for a 256 × 256 × 256 mm (10.1 × 10.1 × 10.1 in) build volume: the dashed box is the printer, the solid cube the largest theoretical part, about 24% of the machine’s volume. Add room for the spool or multicolor unit, cables and ventilation.

Read the Bambu Lab P1S specification analysisWhich projects is it for?
The P1S is a 256 mm enclosed CoreXY FDM printer, the same nominal volume as the A1 but with a different frame and enclosure. It suits regular ABS or ASA projects, or more generally heavier use than an open-frame machine.
The enclosed chassis stabilizes temperature around the printing part, which mainly helps materials that shrink while cooling rather than PLA, which does not need it.
Materials and configuration
The machine is compatible with PLA, PETG, ABS, and ASA per manufacturer profiles, broader compatibility than the A1 thanks to its enclosure.
AMS compatibility varies by bundle; the included AMS version and required accessories need checking precisely before buying rather than assuming.
What the bundle includes or not
The bundle, multicolor system, and accessories need checking on the chosen listing: not every P1S configuration offers the same AMS version or the same included accessories.
An enclosure alone does not guarantee a given material's compatibility; the exact print profile still needs checking for each targeted filament.
Before buying, compare the P1S's spec sheet and the exact bundle contents listed by the retailer (nozzle, bed, multicolor accessories included or not) rather than relying only on the product photo. Warranty terms and after-sales support can also differ between the manufacturer's own store and a third-party retailer, worth checking before comparing two listings. Because the enclosure adds wiring, fans, and sometimes a camera module, it is also worth confirming what maintenance or replacement parts the manufacturer documents for those components before committing to heavy regular use.
Alternatives to compare
For an open-frame chassis at the same volume, the A1 vs P1S comparison covers that exact gap between the two families. For a version with higher maximum temperatures, the P1S vs P2S comparison helps decide between the two machines.
The enclosed 3D printer guide explains what an enclosure genuinely adds, and the ABS and ASA page covers the settings specific to those materials before printing them on an enclosed machine.
