3D Printing Technologies Guides
There are a variety of 3D printing technologies for printing plastics, metals, and various other materials in complex geometric shapes. The original, Stereolithography, came about in the late 1980s.
Since then, other technologies for 3D printing plastic such as Fused Deposition Modeling, as well as Selective Laser Sintering came about in the 1990s, commercialized by companies such as Stratasys, EOS and 3D Systems.
More recently, 3D printing technologies to 3D print metal materials were developed. These include Direct Metal Laser Sintering, as well as lesser known technologies such as Electron Beam Melting in addition to Binder Jetting.
