Which is better for printing ABS and ASA?

Both handle them, but the P1S has the edge: a 300°C hot end and a larger enclosed chamber. The 5M Pro is enclosed with HEPA and carbon filtration and reaches 280°C, which is enough for most ABS and ASA parts.

Which is better for multicolor prints?

The P1S with AMS. It switches between four spools automatically and can chain up to four AMS units for 16 slots. The 5M Pro prints one filament at a time.

The Adventurer 5M Pro. Owners consistently praise its quiet operation. The P1S is enclosed but not tuned for low noise.

Which has a bigger build volume?

The P1S. Its 256 x 256 x 256 mm chamber beats the 5M Pro's 220 x 220 x 220 mm on every axis.

Is the P1S worth stepping up to over the 5M Pro?

Yes if you need multicolor, a larger bed, or regular ABS and ASA work. If you mostly print PLA and PETG and want a fast, quiet, nearly assembled machine, the 5M Pro covers it.

Which is easier to set up?

The 5M Pro. It ships 95% assembled, so you attach the display and spool holder. The P1S takes about 15 minutes with automatic calibration.

Bambu Lab P1S with AMS vs Flashforge Adventurer 5M Pro

Buy the P1S with AMS if you want multicolor printing, a bigger build volume, or engineering filaments like ABS and ASA at scale. The Adventurer 5M Pro is the simpler, quieter, fully enclosed machine for PLA and PETG in a home or classroom, and owners rate it highly. The P1S wins on capacity, automation and the four-spool AMS; the 5M Pro wins on setup time, noise and out-of-box simplicity.

Choose the Bambu Lab P1S with AMS if you print in multiple colors, need a 256 mm cube build volume, or run ABS and ASA regularly.
Choose the Flashforge Adventurer 5M Pro if you want a fast, quiet, fully enclosed printer that is nearly assembled and mostly prints PLA and PETG.
