Today Aleph Objects has announced the release of two new tool heads for their TAZ line of 3D Printers. The Dual Extruder can print with two different materials or two separate colors. It is priced just under $500. The FlexyDually tool head is similar to the Dual Extruder but it allows for the printing of flexible filament from one of the extruders. The Dual Extruder provides .35mm nozzles for finer printing, while the FlexyDually provides .5mm nozzles. Read and see more about this at: http://3dprint.com/23467/lulzbot-dua...r-flexydually/
