36 Facts About Additive Manufacturing

What is Additive Manufacturing?

Additive manufacturing, often called 3D printing, is a process of creating objects by adding material layer by layer. This technology has revolutionized various industries, from aerospace to healthcare.

1. Additive manufacturing builds objects layer by layer, unlike traditional methods that remove material.
2. The process can use various materials, including plastics, metals, and ceramics.
3. It allows for the creation of complex geometries that are difficult or impossible to achieve with traditional manufacturing.
4. 3D printing can reduce waste since it only uses the material needed for the object.
5. The technology can produce customized products on demand, reducing the need for large inventories.

History of Additive Manufacturing

The journey of additive manufacturing began decades ago and has evolved significantly over time.

6. The first 3D printer was created by Chuck Hull in 1983.
7. Hull's invention used a process called stereolithography, which involves curing liquid resin with ultraviolet light.
8. In 1986, Hull founded 3D Systems, one of the first companies to commercialize 3D printing technology.
9. The 1990s saw the development of new 3D printing techniques, including fused deposition modeling (FDM) and selective laser sintering (SLS).
10. By the 2000s, 3D printing had expanded into various industries, including automotive, aerospace, and healthcare.
