A team of EPFL engineers has developed a 3D-printing method that uses light to make objects out of opaque resin in a matter of seconds. Their breakthrough could have promising applications in the biomedical industry, such as to make artificial arteries.

Back in 2017, engineers at EPFL’s Laboratory of Applied Photonic Devices (LAPD), within the School of Engineering, designed a 3D printer capable of fabricating objects almost instantaneously. Now, five years later, the team has improved their printing machine and method, and can produce objects made out of opaque resin—something that was never before …
