Cutting Edge: 3D Printing goes multi

Harvard University researchers have given 3D Printing, a breakthrough in itself, a breakthrough of its own. They found a way to 3D printers to use multiple novels and multiple materials, resulting in a new form of printing called MM3D or multinozzle multimaterial 3D Printing. In this form of printing a single nozzle can inject ink made up of eight different materials. Not just that, each nozzle can change materials 50 times a second. The MM3D printing method can use both solid core materials and flexible ones without unwanted mixing because it uses Y-shaped funnels to prevent backflow.
