Just a few weeks ago we wrote about a new startup called Superior Filament, created by a group of students at Michigan Technological University. The young company began producing their own 3D printer filament last year, using recycled bottles and other plastics to generate new material. They've attracted a good deal of interest - and capital - from startup competitions, but they're now ready to expand into a full-fledged company. An Indiegogo campaign is now live with the goal of raising $10,000 in the next month. Want to contribute? Find out more at 3DPrint.com: https://3dprint.com/137351/superior-filament-indiegogo/ ‎
