Plastikdele til MMU3 (MK3s+)

What is Multi Material Upgrade?

It’s exactly what it sounds like – it’s an optional add-on that allows your single-extruder printer to print with up to 5 colors (materials) at the same time. The MMU3 contains five filament insertion points. Load up to five colors of your choice, slice the object in PrusaSlicer and start the print. The system automatically selects filament using the selector, loads it into the extruder and the printer starts printing. When it’s time to change the color or material, it also happens automatically.

What’s new in MMU3?

• Completely new firmware written from scratch
• Full two-way communication with the printer, Compatible with the MK3S+ and MK4
• LCD screen integration (status messages, real-time information, error codes)
• All plastic parts were redesigned with a focus on easier assembly and maintenance
• New metal parts to make the unit more robust and reliable
• Improved electronics

Efficient multi-color printing

Every time you switch filaments, you need to purge the previous material from the nozzle to prevent cross-contamination. There are various ways to do it and the MMU3 uses an efficient “wipe tower” – it’s a compact, partially hollow block next to the printed object where the filament is purged and the pressure in the nozzle is stabilized. All filament goes into one location and you don’t need to worry about bits of plastic piling around your printer.

We’re offering multiple ways how to save filament and reduce plastic waste – PrusaSlicer gives you options for “wipe into infill” (the printed object’s infill is used as a wipe tower) or you can use “wipe into object” where another object is used as a wipe tower – it will be very colorful but if you, e.g., need a functional part or you will paint it later, it’s a great way to reduce plastic waste to a minimum.
