The Prusa i3 Mk 2 is the hotness in consumer-grade, quality 3D printing right now. And things just keep getting more interesting. We caught up with Josef Průša at Maker Faire Bay Area this weekend to see the multi-material extruder in its final form. It’s an upgrade to the Mk 2 which allows a single hot end to print in four different materials, be it different colors or different types of filament.

It’s safe to say we’ve hit a bit of a plateau with hobby based 3D printers using FDM technology. Print quality is pretty high, they’re about as fast as they’re going to get, and compared to commercial machines they’re a pretty good bang for your buck. So what’s next? What about printing in color?
It is possible to print in color using a regular 3D printer and a bit of patience, but it’s really not economical or efficient. We’ve seen multiple extruder heads for 3D printing as well, but there are many problems with that due to calibration and trailing plastic from one head to another. So what if you could feed multiple color filaments into a single mixing head?
Well, it turns out you can. Earlier this year RepRap ran a Kickstarter for the development of the Diamond Hotend — a single nozzle multi-color extruder. It’s in production now and appears to work quite well. It’s also compatible with many 3D printers as long as the motherboard has triple extruder support.
However, the big question remains — how do you program a colored print? Using Repetier Host actually. You’ll need to export your 3D model in the .AMF file format, but once you do, you’ll be able to configure it for a color print job inside Repetier Host.
