E3D, an England-based 3D printer manufacturer, has just released the initial test results for its forthcoming Cyclops dual hotend extruder. Overcoming traditional issues with 3D printing, including the inability to print in more than one or maybe two colors, the Cyclops is being designed to have interchangable nozzles at a lighterweight than current extruders, all in a small footprint. The Cyclops will soon be released on E3D's website in beta. Check out more details, and some test pictures, in the full article: http://3dprint.com/20697/e3d-cyclops-hotend/ ‎
