Overview of 3D printing methods There are different 3D printing methods for the fabrication of 3D models made of plastic or metal. Where the problems of conventional manufacturing involving subtractive procedures have tended to be difficult or impossible to solve up to now when it comes to filigree elements of components or interior structures, the […]
Stereolithography (SLA) is the oldest 3D printing method. It was invented in 1983 by Chuck Hell and patented in 1986. It is the oldest additive method and is still being used today.
