About the Product

Multi Material Upgrade 2.0 is the second generation of our unique multi-material addon, which enables your 3D printer to print with up to 5 colors at the same time

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.

To unlock the full potential of the MMU 2.0, use our latest Slic3r PE slicing software, which comes with new features, such as Smart wipe tower, Wipe into infill or Wipe into object.

We also offer an option to upgrade the previous MMU 1.0 to the newest 2.0. Visit our e-shop to learn more about the upgrade kit.


Introducing MMU 2.0

How does MMU 2.0 work?

Main Features

Completely redesigned

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.

Up to five materials at the same time

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).

Direct Drive instead of Bowden system

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.

F.I.N.D.A filament sensor

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.

Wipe into infill / into object

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

New Generation Electronics

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.
