3 Multi Material Upgrade introduction
Multi Material Upgrade (MMU) is an addition to the Original Prusa i3 MK2/MK2S 3D printer
which enables printing with up to 4 different materials in one single print.
3.1 How it functions
Instead of traditional use of multiple independent extruders which is considered industry
standard, MMU uses only one hotend with 4 extruder motors and Y splitter. When the
material use is finished during the layer, it is pulled out of the hotend and next one is inserted
back in.
This removes any need to calibrate the position of the nozzle tips and reduces oozing or
artifacts. It is first commercial solution like this.
