help Charles Hull FAQ

Who invented stereolithography 3D printing?

Stereolithography, the world's first 3D printing technology, was invented by American engineer Charles Hull in the 1980s. He developed this method of curing liquid photopolymers into solid plastic layer by layer using ultraviolet light.

What company did Charles Hull found?

In 1986, Charles Hull co-founded 3D Systems Corporation to commercialize his stereolithography 3D printing technology. The company remains one of the largest and most prominent 3D printing and manufacturing companies in the world.

What is the STL file format and how is Charles Hull related to it?

The STL (stereolithography) file format is the standard digital file used by almost all 3D printers today to read object geometry. It was originally created and specified by Charles Hull when he was developing the first SLA machines for 3D Systems.

Did Charles Hull win a National Medal of Technology?

Yes, Charles Hull was awarded the National Medal of Technology and Innovation by the United States government for his monumental contributions to manufacturing. His invention of 3D printing revolutionized prototyping and rapid manufacturing across countless global industries.
