Product description: MMU3 Enclosed for Original Prusa CORE One 3D printers - assembled
The Original Prusa MMU3 is an advanced multi-color and multi-material printing module for the Prusa CORE One printer. It allows you to use up to five filaments in a single print using a single nozzle, offering high quality, high speed, and minimal waste . It's one of the fastest and most efficient single-nozzle MMU solutions on the market. The system automatically changes filament in 35 to 45 seconds, saving countless hours of work when making thousands of changes during a single project. An intelligent nozzle cleaning procedure reduces color mixing, and excess material is directed to a compact cleaning tower placed next to the model. This keeps your workspace clean and significantly reduces filament waste.
MMU3 Enclosed for Original Prusa CORE One 3D printers - assembled. 
Original Prusa MMU3 is an advanced module for multi-color and multi-material printing.
Special features
- Supports up to 5 filaments: multi-color and multi-material printing with a single nozzle
- Very fast material change: filament switching time from 35 to 45 seconds
- Minimized waste: Smart cleaning tower and cleaning functions on the filling or on the model
- Two-way communication with the printer: automatic diagnostics, error messages and current status on the LCD screen
- Full compatibility with filaments from different manufacturers: no material locks
- Large spool support: also compatible with 2 kg reels
- Smooth feed system: cartridge buffer and optimized filament path minimize drag and tangling
- Easy maintenance: the module can be disassembled using basic tools, without glued parts
Practical applications
The MMU3 is fully supported by PrusaSlicer, which allows for intuitive color assignment to specific parts of the model. Tools like the brush, smart infill, and paint bucket are available. Wipe functions on the infill and on another model reduce filament waste and optimize material usage.
For best performance from the MMU3 module in MK4S and CORE One printers, it is recommended to use the standard nozzle instead of the high-flow version. When purchasing the MMU3 module separately for the MK4S or CORE One, a standard quick-change nozzle is included.
