A team of researchers from the University of California at Berkeley (USA) presented a 3D printer that prints with light.
 Created a 3D printer for printing using light.
Reports the edition Engadget about it.
It is worth noting that today there are many different 3D printers, but most of them put the material layer by layer, and therefore there are "seams" on the printed item.
At the same time, scientists from the University of California found a solution to the problem by proposing to print the entire object at once.
Their printer was named "Replicator" ("Replicator") - in honor of the fantastic device from the series "Star Trek", printing objects, food, and so on from almost nothing.
"Replicator" works like a CT scanner. So, initially he studies a computer 3D-model and creates two-dimensional photos from all sides. After that, scientists turn on the projector and project light images onto the surface of a rotating flask filled with a synthetic resin called an acrylate.
This resin consists of liquid polymers, dissolved oxygen and light-sensitive molecules. Under the influence of the light emitted by the projector, the resin gradually hardens when it absorbs enough photons to create the final product.
At the moment, "Replicator" can print only small figures. Scientists have already tested the device by typing a tiny version of the “Thinker” figure in just a couple of minutes.
However, researchers believe that in the future, the printer can be used to create medical components to order.
