3D Printing

3D printing has burst into the mainstream media in recent years, but in reality, it has been around since the 1980s. Patent for stereolithography process was filed in 1984 and the technology used by most 3D printers to date, i.e., fused deposition modeling was developed in 1988. It has been gaining mainstream attention because most of the patents used in manufacturing them have expired, which has made them affordable.
