Now compatible with the Original Prusa i3 MK2.5 and MK3 3D printers, MMU 2.0 went through a major revision, resulting in a simpler and more reliable design. The number of simultaneously supported filaments increased to the total of five, which enables the users to print even more complex and more colorful objects.
MMU 2.0 comes with a redesigned body and a new filament loading mechanism. Instead of the previous Bowden system, the new unit uses a direct-drive feed and a single PTFE tube to lead the selected filament to the extruder. The motorized selector head has a F.I.N.D.A filament sensor and a built-in blade, which prevents filament jamming.

The most significant new features of Original Prusa i3 MMU 2.0
MMU 2.0 has a brand new body with a rotating pulley barrel and a single extruder motor. Load up to 5 filaments and the selector head with a filament-cutting blade will take care of automatic loading and unloading.
The second generation of our Multi Material Upgrade supports up to 5 filaments loaded at the same time. Apart from usual materials like ABS, PETG or PLA, the MMU 2.0 also works great with soluble supports (BVOH or PVA).
We have replaced the previous generation's Bowden system with a new direct-drive mechanism. This change is a major step forward in making the filament loading process more reliable and less prone to jamming.
Meet F.I.N.D.A! It's essentialy a repurposed P.I.N.D.A probe, which now serves as a filament sensor. It works on a mechanical basis - the string of filament lifts a small stainless steel ball and F.I.N.D.A detects its proximity.
Our slicing software Slic3r PE comes with full MMU 2.0 support and a set of useful features, such as Smart wipe tower, Wipe into infill or Wipe into object. These features help you save time and filament.
Powered by a new board, the MMU 2.0 takes advantage of features present on the MK3 itself - such as Trinamic drivers with auto-homing mechanism. The board can be also flashed with updated firmware, so it can learn new tricks in the future.
