Multistruder, Four Filament 3D Printer Extruder

A man named Michael Stabile has launched a Kickstarter project in which he is looking for $65,000 in funding to produce his Multistruder. The Multistruder is a 3D printer extruder which can use 4 different filaments at once. It can even heat all the hot ends at different temperatures so that different materials can also be used as well as different colors. More details on this add-on can be found here.

Here is a picture of some of the cars he printed out with the extruder:

I guess you missed the Quad extruder I released as part of my extruder week on 3Dprintboard.com? You can download, print and build your own open source quad extruder. Details here : http://3dprintboard.com/showthread.p...-Extruder-Week

This looks a little more compact than your quad extruder arrangement (not by much, but every little bit helps). The main feature I see here is the quad-nozzle hotend... Which granted, is pretty slick.
