Is the P1S good for ABS and ASA?

Yes. The enclosed frame and 300°C hotend are the main reasons to pick it over an open printer like the A1. It is not insulated, so large ABS parts can still warp in a cold room.

What does the AMS add?

The AMS holds four spools and swaps filament automatically, so you can print multi-color or multi-material parts without stopping. It also lets you keep four materials loaded at once, and units stack to reach 16 slots.

How big is the build volume?

256 x 256 x 256 mm, which covers most functional parts and helmets in sections. Larger models need to be split.

What comes in the box?

The printer, the AMS unit and the basic setup tools. Filament is not included, so budget for a spool or two.

Does it work with third-party filament?

Yes, it accepts standard 1.75 mm filament, though Bambu's own profiles and RFID-tagged spools are the smoothest to use with the AMS.

How does the P1S compare with the P1P?

The P1S adds a full enclosure, an activated carbon filter and a chamber fan over the open-frame P1P, which is what makes ABS and ASA practical. Both share the same build volume and motion system.
