Fused Deposition Modelling
Fused Deposition Modelling, commonly known as FDM is a process of 3D Printing in which the molten wire form plastic material is fused layer by layer to build the 3D Object.
Stereolithography, commonly know as SLA or DLP is a type of 3D Printing in which an ultraviolet or laser light source is used to cure a photosensitive resin layer by layer to create a 3D Object.
Selective Laser Sintering
Selective laser sintering commonly know as SLS uses a laser as the power source to sinter powdered material thereby binding the material together to create a 3D Object.
Direct Metal Laser Sintering
Selective laser melting (SLM), also known as direct metal laser sintering (DMLS) uses a high power-density laser to melt and fuse metallic powders together, thereby creating a 3D Object.
