Original Prusa MMU3 (for MK4S/MK3.9S)

Thanks to the Original Prusa MMU3 assembled unit it is possible to use up to 5 colours with only 1 nozzle. This smart upgrade for the Original Prusa 3D printer automatically switches between different filaments, allowing you to create the most colourful projects.

Filament saving
The firmware and smart design ensure that filament can be changed extra fast with minimal filament waste. In addition, there are perfect colour transitions and the wipe tower is built efficiently. It is also possible to use the 'wipe to infill' option or the 'wipe to object' option, which both help to save filament.

User friendly
The filament is fed through a PTFE tube to a buffer and then to the 3D printer, preventing resistance and tangling of the filament. If there are any problems, the MMU3 can detect and fix them itself. An extensive error message is also sent to the LCD screen of the 3D printer. Manual adjustments can also be easily made via the LCD screen or via the buttons on the unit.

Please note: the MMU3 works best with a standard nozzle instead of a high-flow nozzle.
