A new type of 3D printing could dramatically speed up the way tiny, complex objects are made. Instead of slowly building an object one layer at a time, researchers have developed a technique that can create an entire 3D structure—including hollow spaces inside it—with a single burst of laser light. Scientists at the University of […] The post New 3D Printing Technology Creates Complex Objects in Just 7.5 Seconds appeared first on Knowridge Science Report .
