Enclosure and cooling
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.
Material qualifications
The supplied nozzle is stainless steel. The table separates ideal materials from PA and PC, which it labels capable. Fiber-filled materials require checking the appropriate wear-resistant hardware and material guidance instead of assuming that every filament is supported.
Introduced in 2023.
Manufacturer retrospective dates P1S introduction to July 2023.
