Now you can create full-fledged 3D objects in just a few seconds.
Behind the new technology are scientists from the Laboratory for Applied Photon Devices (LAPD) at Swiss Federal Institute of Technology in Lausanne in Switzerland. The main feature of the new method is that the object is created not in layers (as usually happens with 3D printing), but as a whole. Today, there are restrictions on the size and complexity of objects that can be created in this way, but researchers are not going to stop there.
The technology uses a photosensitive polymer as ink, and the technology itself is based on the tomography principle. The liquid is poured into a rotating container, inside which a printed object is formed. This happens thanks to lasers, the rays of which are focused at certain points inside the container, causing the substance to solidify. At the end, the excess ink is drained and the job can be considered to be done.
This method allows you to print 3D objects in record 30 seconds. Though their size and complexity are limited by the printer itself, so now scientists are working on improving the machine.
