The team did away with the traditional nozzle design, which uses a “pinch-wheel” mechanism to feed through the plastic, replacing it with a screw mechanism that turns within the printhead.
Although 3D printing can speed up production times and make it easier to create products and components from scratch, MIT engineers are taking it one step further. The team has developed a new desktop 3D printer that performs up to 10 times faster than existing commercial counterparts.
Most common desktop 3D printers are able to print a few centimetres-sized blocks in an hour. However, the new design can print similar sized objects in a matter of minutes.
