Prusa’s Multi Material upgrade for the i3 MK2/s printer brings 4-color printing without compromising the single color printing quality and workflow.

Smooth Transitions

You don’t have to commit to a particular extruder when slicing, which makes switching between colors as simple as selecting the appropriate extruder number in software. But be prepared: Multimaterial printing is a long process, especially by 3D printing terms.

Two nitpicky comments: the amount of wasted filament as part of the purge plate process, and upon canceling a print the filament is expelled by default.

Great Value, Broad Appeal

The MK2S MM printer blew through our testing probes and then went on to dazzle us with its multicolor tricks. At a mere $299, the MM upgrade is a no-brainer.
