Product description: MMU3 Enclosed for Original Prusa CORE One 3D printers - Full Kit
The Original Prusa MMU3 Enclosed module is an innovative solution enabling 3D printing using up to five filaments in a single print . Thanks to optimized firmware and bidirectional printer communication, the MMU3 offers reliable, fast, and convenient multi-color printing from a single nozzle. The Enclosed version is specifically tuned to maintain the CORE One's enclosed chamber , ensuring consistent temperature conditions inside the printer. The kit includes everything needed to integrate the MMU3 module with the printer, including a top cover with a PTFE tube feedthrough.

The MMU3 spool racks can accommodate a wide range of filaments—even large 2kg spools. You can also design custom racks yourself.
Main features of MMU3
- Multi-material printing up to 5 filaments: allows automatic color and material changes during a single print
- Optimized filament change time: 35 to 45 seconds, which significantly reduces printing time
- Enclosed version: retains the fully enclosed CORE One chamber, ensuring stable printing conditions
- Minimal waste: thanks to intelligent head cleaning and cleaning options on model/fill
- Full compatibility with PrusaSlicer and EasyPrint: allows you to conveniently prepare models for printing from your browser
- Advanced printer communication: error diagnostics, status information on the LCD screen, quick user intervention

What does the MMU3 module offer for the Prusa CORE One printer?
The MMU3 module significantly expands the capabilities of the Prusa CORE One printer, allowing you to automatically print with up to five different filaments in a single project . You gain the ability to create multi-color models, elements combining different material properties or functional structures using soluble supports. The MMU3 increases versatility, saves time, and minimizes waste , offering a solution close to professional multi-head systems while maintaining a compact design and attractive price. With its high reliability and intuitive operation, the MMU3 is an ideal choice for both hobbyists and prototyping professionals.
PrusaSlicer and EasyPrint - MMU3 support
PrusaSlicer is an advanced 3D model preparation tool that fully supports MMU3, offering precise color assignment and advanced slicing options. Features like the smart wipe tower, infill wipe, and model wipe allow for significant reductions in material consumption and sharp color transitions. EasyPrint, an intuitive online application that runs in a browser or on a smartphone, allows for quick print preparation without the need for software installation. It even supports intelligent painting of single-color models, making it the perfect complement to the MMU3 for mobile and home work environments.
