What owners say
Beyond impressed. Wicked fast, quiet, and the build quality is crazy impressive after 3000+ hours on other Bambu printers.
H2D owner, Bambu Lab Community ForumFor elite crafters. The H2D redefines what a desktop printer can do.
H2D owner, Tom's HardwareThe dual-nozzle system cuts print times by a factor of two. The speed increase is amazing.
H2D owner, r/BambuLabMy MK3 ran for 5 years without a single failed print. The MK4S continues that legacy.
Prusa MK4S owner, r/prusa3dIf reliability is your #1 priority, nothing beats Prusa. Nothing.

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.
