Multi Material Upgrade 2S (MMU2S) is a brand new and 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, a new filament sensor, and a standalone filament buffer, the MMU2S is more reliable than ever before.
This product is supplied as a kit - you must assemble it by yourself!
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.
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.
