FDM (Fused Deposition Modeling) 3D printers are a popular type of desktop 3D printer that use a filament of thermoplastic material, typically PLA or ABS, to create 3D objects layer by layer.

A resin 3D printer, also known as a stereolithography (SLA) printer, is a type of 3D printer that uses a liquid resin material to create 3D objects layer by layer. The resin is cured by a light source, usually a laser or an ultraviolet (UV) light, which solidifies the resin layer by layer, forming the final object.
