In an industrial context, 3D printing is mostly referred to as additive manufacturing. Additive manufacturing is suitable for the production of visual and functional prototypes (rapid prototyping), end products (rapid manufacturing) as well as tools and molds (rapid tooling). With 3D printing, three-dimensional objects are printed with a 3D printer, even in the field of medical technology. Although one speaks of "printing", 3D printing is more than just the application of material to a carrier material. Combined with laser technology, aluminum powder e.g. melt into an aluminum object. 3D printing will change the entire production so massively in the next few years, including in medical technology.
