Additive manufacturing, also commonly referred to as 3D printing, is a manufacturing process by which material is added, layer by layer, to build a part. The process starts with a 3D model that is designed in the user’s native CAD program. That part is then analyzed and sliced into in many sections to create a build plan for the part. The popular technologies for additive manufacturing include Stereolithography (SLA), Selective Laser Sintering (SLS), Direct Metal Laser Sintering (DMLS), Selective Laser Melting (SLM), and Fused Filament Fabrication (FFF). There are other technologies as well.
