Chinese Scientists Unveil Lightning-Fast 3D Printing Innovation

2/26/2026

Summary

Story summary

Chinese scientists from Tsinghua University have introduced a holographic projection–based 3D printing technique that solidifies liquid into three-dimensional objects in under a second.
The method replaces traditional layer-by-layer, mechanical scanning approaches that often take minutes or hours.
The technique achieves high speed and precision, printing millimetre-scale components in about 0.6 seconds.
The innovation could enhance medical uses and military repairs, potentially transforming the 3D printing landscape.
