A closed chamber is the biggest favor you can do a room full of students, and the P2S has one. The hot end and the moving toolhead sit behind panels, the frame swallows most of the mechanical noise, and the chamber holds 50 °C for materials that warp on an open bench. At 18 by 22 by 18 inches it wants a permanent bench rather than a cart that gets wheeled into a cupboard on Fridays.
What settled it for us is how little attention it asks for between prints. Calibration is automatic, nozzles swap quickly, and the AI failure detection stops a job when the extrusion starts to curl off the plate instead of burying it under an hour of spaghetti. Setup is quoted at 15 minutes, which matters more than it sounds: a teacher can unpack it at 7:30 and have a test print running before first period.
The AMS 2 Pro is the part we didn't expect to care about and now would not give up. It holds spools and dries them at up to 65 °C, which is the answer to the school-storage problem where filament sits on a shelf through a humid summer and prints badly in September. It handles multi-color too; with filaments loaded, a class can print color-coded parts without anyone touching a spool mid-job. Younger students still need a hand loading it, so fill it before the lesson rather than during one.
The rest is standard Bambu ecosystem: the MakerWorld library for lesson-ready models, Bambu Studio and the Handy app for queueing jobs. What the door costs you is access. A first layer that lifts has to wait until you open the machine, and by then the print is usually a loss. We take that trade for the safety margin it buys.
Pros
- Enclosed chamber keeps hands off hot, moving parts
- Automatic calibration and AI failure detection
- AMS 2 Pro dries filament at up to 65 °C
- 15-minute setup and quiet running
Cons
- 46.3 pounds; wants a permanent bench
- The most expensive setup in this group
Our pick for a machine that lives on a classroom bench all year: enclosed, self-calibrating, and quiet enough to talk over.
