What owners say
16 colors on an enclosed CoreXY for under €500 was not on my 2026 bingo card. Anycubic is swinging hard at Bambu's multi-color dominance.

Pros & Cons

- +Fully enclosed CoreXY handles ABS, ASA, and engineering filaments without warping
- +44dB quiet mode is unusually low for a 600mm/s CoreXY — apartment-friendly
- −Brand new product — early adopter risk on firmware and ACE 2 Pro reliability
- −Anycubic slicer still trails Bambu Studio on automation and profile polish
X2D
- +Dual nozzle at $649, a third of what the H2D costs
- +65C heated chamber handles any engineering material you'll realistically use
- +31 sensors and a servo extruder with real-time flow compensation
- −Same build volume as the P2S, not the H2D's bigger 325mm
- −Dual-extrusion mode shrinks the usable X to around 235.5mm
Buy these with it
A printer does nothing without these. Grab them in the same order.
- ELEGOO PLA filament, 1kgThe easy filament to start on. Prints at low temperatures and warps less.
- ELEGOO PETG filament, 1kgTougher and more heat tolerant than PLA, for parts that get handled or sit in the sun.
- SUNLU filament dryer S1 PlusWet filament causes stringing and rough surfaces. A dryer fixes that before you blame the printer.
