3D printing was patented by Chuck Hull in 1984 using stereolithography

Ultraviolet lasers solidifying liquid photopolymer resin layer by layer created 3D objects

Chuck Hull invented stereolithography in 1984, laying the foundation for modern additive manufacturing. The process used a focused ultraviolet laser beam to cure and harden liquid photopolymer resin inside a vat, building three-dimensional physical models layer upon layer. Modern 3D printers use plastics, metals, and concrete to fabricate custom industrial components.
