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 profileP-series filament printer with a 256 mm cubic build volume.
P2S uses a flap-controlled airflow system and servo extrusion monitoring. The launch description distinguishes outside-air cooling from heat retention inside the enclosure; it does not establish an actively heated chamber temperature.
