Which is better for printing ABS and ASA?

The P2S. Both are enclosed and reach 300°C, but the P2S adds a 110°C bed, carbon filtration and adaptive airflow, which matter for styrene fumes and warping. The P1S with AMS still prints ABS and ASA, just with less fume control.

Only if you want multi-color or multi-material prints without swapping spools by hand. The P1S bundle includes the AMS; on the P2S it is a separate combo, so add that cost when comparing.

Is the P2S worth the extra money?

If you print engineering materials or leave long prints unattended, yes. AI failure detection, filtration and the servo extruder are real upgrades. If you mainly print PLA in several colors, the P1S with AMS covers more of what you need.

Which has better print quality?

Reviewers describe the P2S as producing clean, professional-level prints with little adjustment. The P1S uses the same build volume and hotend temperature, so quality is close, but the P2S has the newer extruder and monitoring.

Which is easier for a beginner?

The P2S, according to reviewers, who cite intelligent calibration and a gentle learning curve. The P1S also has auto bed leveling and a 15-minute setup, so neither is hard to start with.

Both have a 256 x 256 x 256 mm build volume. One P2S reviewer notes the machine itself takes up a lot of space, so measure your bench before buying either.

Bambu Lab P1S with AMS vs Bambu Lab P2S

Buy the P2S if you want the newer machine: AI spaghetti detection, active carbon filtration, a servo extruder and a 1080p camera, backed by 47 ratings at 4.9. Buy the P1S with AMS if multi-color printing matters more than those upgrades, since the AMS is the headline of that bundle. The P1S with AMS has been seen as low as $11.36 and as high as $349.00 since October 28, 2026; the P2S has ranged from $29.84 to $449.00 since the same date. Check current store prices on both before deciding, because those spreads are wide.
