While there are many varieties in 3D printer technologies, there are seven most common types. All printing technologies build parts in discrete slices called layers. Fused Filament Fabrication (FFF, also known as Fused Deposition Modeling) Continuous Filament Fabrication (CFF) Atomic Diffusion Additive Manufacturing (ADAM, also known as Bound Powder Deposition) Selective Laser Sintering/Melting (SLS/SLM, also known as DMLS for metal) Direct Light Processing (DLP) Stereolithography (SLA) Binder Jetting Extrusion FFF (Fused Filament Fabrication) Much like traditional printers use a variety of technologies. The most commonly known is fused filament fabrication (FFF), also known as fused deposition modeling (FDM). most machines utilize this technology. In FFF, the printer heats up thermoplastic…
