China sets record for speed in 3D printing
Scientists at Tsinghua University in China have developed a groundbreaking 3D printing technology capable of producing complex millimetre-scale objects in just 0.6 seconds. The finest elements reach sizes of up to 12 micrometres, while the volumetric printing speed achieves up to 333 cubic millimetres per second. This represents a significant reduction in manufacturing time for high-precision parts.

Unlike traditional methods that typically require tens of minutes or even hours due to a trade-off between speed and accuracy as well as constraints related to material viscosity and container design, the new DISH technology (digital incoherent synthesis of holographic light fields) controls holographic light fields. It forms the entire volume simultaneously using a set of light profiles calculated as a hologram, rather than layering sequentially.
This breakthrough could revolutionise fields requiring fast and highly accurate 3D printing, including micro-component manufacturing, medical implants, and complex prototyping. The technology is expected to find broad industrial applications in the near future.
