China unveils ultrafast holographic 3D printing at 0.6 seconds
Researchers at Tsinghua University have introduced Digital Incoherent Synthesis of Holographic light fields (DISH), a holographic-based volumetric 3D printing method that can fabricate millimeter-scale objects in 0.6 seconds with 12‑micrometer precision. By projecting holographic light from multiple angles in a resin, without moving parts or layered drying, the system achieves about 333 cubic millimeters per second and could enable rapid, high-resolution production for biomedicine, nanotechnology, micro-robotics, and flexible electronics.
