Bambu Lab P1S Combo and Bambu Lab A1 Combo compared by build volume, materials and enclosure, workflow.
The practical choice turns on materials and enclosure, then on the constraints in your own setup.
Winner by situation
For materials and enclosure, Bambu Lab P1S Combo records “The printer has an enclosed build area. Its recorded material path covers PLA and ABS” and Bambu Lab A1 Combo with LED Kit records “The printer has an open-frame build area. Its recorded material path covers PLA”. Materials and construction can set care, compatibility and placement limits. They do not prove durability on their own.
Automatic calibration removes several manual steps before a first print.
An enclosed chamber reduces drafts that can warp ABS.
A direct-drive toolhead gives flexible TPU a short, controlled filament path.
