Original Prusa i3 MK2.5S/MK3S Multi Material 2S upgrade kit (MMU2S)

New product

Multi Material Upgrade 2S (MMU2S) is a brand new an improved version of the Multi Material Upgrade 2.0 - our unique multi-material addon, which enables your 3D printer to print with up to 5 colors at the same time. With an easier calibration process, new filament sensor and a standalone filament buffer, the MMU2S is more reliable than ever before.

If you already have MMU for MK2/S, you should buy Multi Material upgrade kit - from MK2 to MK2.5/MK3

This product is supplied as a kit - you must assemble it by yourself!

More info

Multi Material Upgrade 2S (MMU2S) is a brand new an improved version of the Multi Material Upgrade 2.0. With an easier calibration process, new filament sensor and a standalone filament buffer, the MMU2S is more reliable than ever before.

WITH THE ORIGINAL PRUSA MMU2S WE ARE INTRODUCING:

NEW FILAMENT SENSOR

With the MMU2S we managed to sense not only that the filament is present, but that it actually reached the Bondtech gears. The filament sensor detects when the idler doors open a bit as the filament pushes Bondtechs apart. MMU2S is much more reliable regarding reloading filaments and the calibration process is also simplified.

FILAMENT BUFFER

The MMU2S comes with the filament buffer, a device designed to prevent filament tangling during loading / unloading process. The buffer allows you to position the five filament spools more freely and also saves valuable space on your desk.

THOROUGHLY TESTED

The testing process of the MMU2S took 2 months to finish, we used 20 printers and we printed 478 test blocks designed to test frequent switching of all five filaments. The total value of filament changes was nearly 600.000. More than 93 % of this prints were successfully completed.

PLEASE NOTE IF YOU ORDER TOGETHER WITH MK3S, IT WILL BE SHIPPED TOGETHER LATER. We suggest making separate orders.

Multi Material Upgrade 2S (MMU2S) is the second generation of our unique multi-material addon, which enables your Original Prusa i3 MK2.5S/MK3S 3D printer to print with up to 5 filaments at the same time.

Compared to MMU1, the new MMU2S 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.

MMU2S 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.

Introducing MMU2S

How does MMU2S work?


MAIN FEATURES

The most significant new features of Original Prusa i3 MMU2S

COMPLETELY REDESIGNED

MMU2S 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.

FIVE MATERIALS

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

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 / 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.

FILAMENT BUFFER INCLUDED

The MMU2S comes with the Filament Buffer, a device designed to prevent filament tangling during loading / unloading process. The buffer allows you to position the five filament spools more freely and also saves valuable space on your desk.

Great concept, but needs a little more development. Better for e

I've had this upgrade for my MK3 since late November. As with the MK3, the assembly was straightforward and only took me a day. However, it takes extremely precise tweaking of both physical parts and slicer settings to get good results. Took me more than a week to get consistent prints, but that was a long time ago and the firmware and hardware have been improved quite a bit since then. You may need to mess around with the perfect spring tensions, filament sensor height, and retraction settings before getting consistent results. But trust me, you'll get good prints eventually, but just be patient. If you have good experience in 3D printing troubleshooting and understand how the parts of this upgrade work, you should be fine in troubleshooting it yourself or people from forums can help you out. Make sure you know what you're doing with this! It may take a while to get good results.
However, this is still basically one of the best options for multimaterial printing on the market as of early 2019 for this price. Just be aware of what you're getting into.
I hope this helps, and good luck!
