The catch
Bambu Lab P1S Combo
Color changes purge filament since the nozzle is shared.
Side by side
An enclosure points to the P1S Combo, while easier access to an open bed points to the A1 Combo.
Before you buy
Bambu Lab P1S Combo is the better match for “Turn out functional parts quickly” and “Get less warping on ABS prints”. Bambu Lab A1 Combo with LED Kit is the better match for “Begin your first project” and “Run flexible TPU”.
Where this comes from
This lines up the current strong and useful fit ratings for the exact products. It does not roll them into one overall score.
The catch

The catch
ABS and ASA are a poor match for an open frame.

How the Bambu Lab P1S Combo and Bambu Lab A1 Combo stack up on build volume, materials, enclosure and workflow.
This one comes down to materials and enclosure first, then to the limits of your own setup.
Which one fits
Bambu Lab P1S Combo lists “The printer has an enclosed build area. Its recorded material path covers PLA and ABS” for materials and enclosure, while Bambu Lab A1 Combo with LED Kit lists “The printer has an open-frame build area. Its recorded material path covers PLA”. Materials and build can limit care, compatibility and placement. They do not prove durability by themselves.
Automatic calibration takes several manual steps off your list before the first print.
Drafts can warp ABS, and an enclosed chamber cuts them down.
Flexible TPU gets a short, controlled filament path from a direct-drive toolhead.
In practice
Bambu Lab P1S Combo is the better match for “Turn out functional parts quickly” and “Get less warping on ABS prints”. Bambu Lab A1 Combo with LED Kit is the better match for “Begin your first project” and “Run flexible TPU”.

Trade-offs
Decision guide
Need an enclosure? That is the P1S Combo. Prefer simple access to an open bed? That is the A1 Combo.
A 256 mm cube and four-color hardware come with both.
The P1S is an enclosed CoreXY, the A1 an open bed slinger.
Both are listed at a 500 mm/s top speed.
