Additive manufacturing, more commonly known as 3D printing, is the process of building three-dimensional objects by uploading computer-aided design (CAD) files into a 3D printer. With a few clicks and commands, the 3D printer then extrudes the chosen material — usually thermoplastics, photopolymers, and metals — layer by layer, until a solid three-dimensional rendering of the object is completed.
The technology has come a long way since its inception in 1974 by British chemist David E.H. Jones, whose groundbreaking concept of using monomers to create solid objects has been developed over the years. And today, there is still plenty of room for exciting innovation.
