Ultrafast 3D printing method creates complex objects in under a second

High-speed 3D printing has just gotten a lot faster. Researchers from Tsinghua University in China have developed a new high-speed printing technology capable of creating complex millimeter-scale objects in just 0.6 seconds. Traditional 3D printing is often slow because it builds objects one thin layer at a time. While a newer method called volumetric printing, which uses light to shape an object, has become progressively faster in recent years, it has hit a major speed bump.
