Charles W. Hull

Charles W. Hull was an American scientist and engineer who pioneered the development of 3D printing technology. In the early 1980s, he invented stereolithography, a process that builds three-dimensional objects by curing liquid resin layer by layer using ultraviolet light. This innovation revolutionized manufacturing, prototyping, and design by enabling the quick and precise creation of complex parts directly from digital models. Hull’s work laid the foundation for modern additive manufacturing, impacting industries from aerospace to healthcare. His contributions have significantly advanced how products are designed and produced, making 3D printing a practical and widely used technology today.
