Tsinghua Demonstrates Rapid High-Resolution Volumetric Printing
Researchers at Tsinghua and Zhejiang universities publish in Nature a volumetric 3D printing method, Digital Incoherent Synthesis of Holographic Light Fields (DISH), that fabricates millimetre-scale objects in 0.6 seconds while maintaining uniform 19 μm resolution across a 1 cm depth. DISH uses a rotating periscope, high-rate binary projections, and holographic wave-optics modeling to overcome focal-depth limits, achieving 333 mm³/s throughput and compatibility with low-viscosity resins. This enables sequential flow-based production without mould changes.
