P1S vs A2L
Enclosed standard format vs open XL bed-slinger
Which one should I buy?
Different shapes of the same budget: the P1S at $399 gives you an enclosure for ABS/ASA in a 256 mm cube; the A2L at $469 gives you a much bigger 330 × 320 × 325 mm volume but no enclosure. Pick by material: enclosed P1S for warp-prone filaments, open A2L for big PLA/PETG prints.

Strengths: P1S vs A2L
P1S
- You print ABS/ASA or want fume filtration
- CoreXY speed and a proven platform matter
- Your parts fit in 256 mm
A2L
- You want the largest budget Bambu volume (330 × 320 × 325 mm)
- PLA/PETG covers your materials
- 19-color printing (AMS lite plus box AMS) or the cutting plotter appeals to you

Enclosure or volume, pick one
This is the clearest either-or in the current lineup. The P1S is CoreXY, enclosed with activated carbon filtration, happy with ABS and ASA, but limited to 256 mm. The A2L (June 2026) is an open-frame bed-slinger with 105% more build volume, up to 19 colors with one AMS lite plus up to four box-style AMS units, and an optional cutting plotter, but no chamber: ABS/ASA will warp on anything large.
For decorative prints, cosplay parts and big functional PLA/PETG pieces, the A2L's volume wins. For engineering-adjacent materials, garages that get cold, or fume-sensitive spaces, the enclosed P1S wins. At $70 apart, price is not the decider; your filament is.
Get the P1S if...
- You print ABS/ASA or want fume filtration
- CoreXY speed and a proven platform matter
- Your parts fit in 256 mm
Get the A2L if...
- You want the largest budget Bambu volume (330 × 320 × 325 mm)
- PLA/PETG covers your materials
- 19-color printing (AMS lite plus box AMS) or the cutting plotter appeals to you

What about A2L vs the bigger H-series volumes?
The H2S offers 340 × 320 × 340 mm enclosed at $1,199, so the A2L delivers almost H-series volume, open, for 39% of the price. That is its whole pitch.
