The building blocks of 3D printing can be found in mid-nineteenth century Paris and the work of Sculptor and Photographer, François Willeme.
Willeme patented a photographic technique to capture and create 3D data models which were able to be of use in recreating solid objects. Additional work in the latter part of the nineteenth century to create topological relief maps, in a layer-by-layer fabrication approach, was done by Joseph Blanther.
These concepts would be apparent in the first practical demonstration of 3D Printing in the 1980s, when Charles Hull made the history books by inventing Stereolithography (SLA) with Selective Laser Sintering (SLS) to follow quickly afterwards. Ever since, additive manufacturing technology has grown in both materials and methodology resulting in more accurate structures created in more workable materials with additional demanding dimensional tolerances and feature sizes to the […]
