Germany-based ViscoTec is one of the leaders in precision dosing systems and components. Having realized the similarities between dosing technology and FFF/FDM 3D printers, ViscoTec is now entering the 3D printing space, focusing on the extrusion of viscous materials. The company is not building their own 3D printer, but is concentrating on the print head and software, providing ultra precise volumetric dosing via their preeflow system. While paste extruding machines are not in themselves completely new, ViscoTec has achieved unprecedented precision and accuracy in fine nozzle diameters to disperse viscous materials. Depending on the nature of the particular material, they are currently able to print at a layer thickness of 0.2mm, at a speed as as fast as 1 ml/minute. Check out details, and see a video of the tech in action, over in the full article: http://3dprint.com/29913/viscotec-do...aste-extruder/ ‎
