Description
Prusa MMU3 - Assembled Unit expands Prusa MK4S and MK3.9S printers with multi-color and multi-material printing using a single nozzle. The system allows up to 5 filaments to be loaded simultaneously and automatically switched during a single print without manual intervention.
Material changes are handled by a selector controlled by dedicated firmware and take on average 35 - 45 s. In projects requiring hundreds or thousands of tool changes, this significantly reduces total print time compared to slower single-nozzle multi-material systems. Excess material generated during color transitions is directed to a wipe tower or used within the infill structure, depending on PrusaSlicer settings.
The Assembled Unit version is delivered as a fully assembled MMU3 module, reducing preparation time compared to the Full Kit variant intended for self-assembly. This option is intended for users who expect fast installation and minimal assembly work.
The filament feeding system uses a buffer unit and PTFE tubes to guide the material to the module and then to the printer’s extruder. The design reduces movement resistance and minimizes the risk of filament tangling. Bidirectional communication with the printer firmware enables error diagnostics, status messages displayed on the LCD screen, and control via the printer menu or the module’s hardware buttons.
MMU3 is fully supported in PrusaSlicer, which allows assigning colors to selected parts of the model, defining material changes at specific layers, and optimizing filament usage through wipe-to-infill or wipe-to-object options. To reduce material waste, the use of a standard nozzle is recommended instead of a high-flow version.
