Both advertise a 256 mm cubic build volume. The enclosure, motion system and feeder ecosystem are the differences to evaluate against your material and workspace.
The A1 is open-frame; the P1S is enclosed. If your material requires specific thermal conditions, check the complete manufacturer guidance rather than treating an enclosure as automatic compatibility.
A1 uses AMS lite. P1S uses compatible AMS configurations and any required adapters. An accessory from one family should not be assumed to work with the other.
Equal build volume does not imply equal noise, print quality or real job duration. We have no hands-on measurements for those criteria. Use this comparison to form a shortlist and verify the exact offer.
256 × 256 × 256 mm
More space on every axis than the A1 mini, while keeping the A1 family workflow.
An open frame does not provide the same thermal conditions as an enclosed printer. Choose materials accordingly.
Specifications and seller
256 × 256 × 256 mm
The same nominal volume as the A1, with an enclosure and a different motion system.
Check the precise AMS version, adapters and accessories included. Enclosure alone does not establish material suitability.
