How the two machines differ on paper: build volume, process, enclosure, nozzle temperature, launch year and the materials each manufacturer names. This is a specification comparison, not a hands-on test.

Published specifications don't settle print quality, reliability or noise. Compare the exact configuration, bundled accessories, regional price and support with each manufacturer, and check that the materials you need are supported on the configuration you'd buy.

Enclosed filament printer with a 256 mm nominal cubic build volume.
The P1S specification lists a plastic-and-glass enclosure, an auxiliary part-cooling fan, a chamber-regulator fan and a control-board fan. These distinguish its configuration from the open-frame P1P shown in the same comparison.
Full sourced profileEnclosed X1-series filament printer with a 300°C hotend.
The technical sheet specifies hardened-steel extrusion gears and nozzle, an activated-carbon filter, lidar and a chamber camera. Filament odometry is an AMS-dependent option. The quoted 32 mm³/s hotend flow was measured using Bambu ABS at 280 °C on a 150 × 150 mm single-wall model; it is not a general flow guarantee for every filament.
