3D printing uses a variety of different types of technologies. Stereolithography (SLA) focuses a beam of ultraviolet light onto a vat of liquid photocurable resin, drawing out the 3D model one ...

In a lab at Zhejiang University, a graduate student added a common chemical to a polymer mixture—and got unexpected results.

Cracking the problem of waste in 3D printing In one version of 3D printing, a model is built layer by layer using light to harden a liquid resin, this process is called vat photopolymerisation.
