The new approach to 3D printing prints the entire object using light and special synthetic resin. This new technique is much faster and has other benefits. It can only print small objects now, but there is a lot of potential.
The researchers have nicknamed the printer “the replicator”. It creates objects much like a reverse computed tomography. The object to be replicated is scanned from multiple angles. Those scans are then projected on a tube with the resin. This technique allows printing in minutes rather than the hours of a standard 3D printer.
