Who created rapid prototyping?

The concept of rapid prototyping has evolved over time, and it's difficult to attribute its creation to a single individual or entity. However, the development of rapid prototyping technologies can be traced back to the 1980s. One of the earliest and most influential technologies in this area was stereolithography.

Stereolithography, a 3D printing technology, was invented by Charles W. Hull in 1983. Hull co-founded 3D Systems, a company that played a key role in the development and commercialization of rapid prototyping technologies. Stereolithography involves using a laser to solidify layers of liquid resin to create a three-dimensional object. This technology marked the beginning of the rapid prototyping era, allowing engineers and designers to quickly create physical prototypes of their designs.

While Charles W. Hull is often credited with the invention of stereolithography, it's important to note that rapid prototyping as a field involves contributions from multiple individuals and researchers who have worked on various technologies and techniques to accelerate the prototyping process.
