Chinese scientists show ultra-fast 3D printing technique
Chinese scientists from Tsinghua University in China have developed a new 3D printing technique to create three-dimensional objects in under a second, TASS reports

Standard printers use a printing nozzle, building objects layer by layer, the process that takes minutes or hours. According to South China Morning Post, the researches placed printing material inside a transparent container and, with the flip of a switch, transformed it into a solid structure using a holographic projection in just 0.6 seconds, the time it takes to print an object of up to 1 centimetre.
Using a fast-rotating periscope and a high-speed micromirror device, aimed light at the photosensitive material from different angles at the same time, causing the entire construction to harden instantly.
Once printed, gravity makes the finished product settle. Now, it can be removed and the cycle can be repeated, keeping production going. The result is remarkable not only for its record speed, but also for its applicability to micro-optics, electronics, and biomedicine, the teams said. In the future, the scientists plan to refine the projection system by using multiple beams or even various colours of light to control complex materials more accurately.
