Advanced Automated Multi-Tools has launched a Kickstarter campaign for its CollideOScope Multi-Filament Print Head which allows you to use 7 extruders in an easy and affordable manner. The campaign seeks to raise $8, 250 by November 9, 2015 with a delivery date in January 2016. You can pledge as little as $187 and received the basic print head without much electronics, or $830 will get you one with "the works." The idea is practical, affordable, and has been enhanced with Simplify3D software. There are still challenges, but the company looks forward to seeing how consumers use and perfect the device.
