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 \u003cstrong\u003eautomatically selects filament\u003c\/strong\u003e using the selector, loads it into the extruder and the printer starts printing. When it’s time to \u003cstrong\u003echange the color or material\u003c\/strong\u003e, it also happens automatically.\u003c\/p\u003e\n\u003ch2\u003e\u003cspan data-code=\"3840\"\u003eWhat's new in MMU3?\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompletely new firmware\u003c\/strong\u003e written from scratch\u003c\/li\u003e\n\u003cli\u003eFull two-way communication with the printer, Compatible with the MK3S+ and MK4\u003c\/li\u003e\n\u003cli\u003eLCD screen integration (status messages, real-time information, error codes)\u003c\/li\u003e\n\u003cli\u003eAll plastic parts were \u003cstrong\u003eredesigned\u003c\/strong\u003e with a focus on \u003cstrong\u003eeasier assembly and maintenance\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eNew metal parts to make the unit \u003cstrong\u003emore robust and reliable\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eImproved electronics\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cspan data-code=\"3842\"\u003eEfficient multi-color printing\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003eEvery 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 \u003cstrong\u003eefficient “wipe tower” \u003c\/strong\u003e- 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWe’re offering multiple ways how to save filament\u003c\/strong\u003e and reduce plastic waste - PrusaSlicer gives you options for \u003cstrong\u003e“wipe into infill”\u003c\/strong\u003e (the printed object’s infill is used as a wipe tower) or you can use \u003cstrong\u003e“wipe into object”\u003c\/strong\u003e 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 \u003cstrong\u003egreat way to reduce plastic waste to a minimum.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMain Features\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-code=\"4008\"\u003eEver since the release of the MMU2S, we’ve been collecting and analyzing feedback from our community.
