FDM(Fused Deposition Modeling) is a filament based technology, where the material is extruded through the heated nozzle layer by layer onto a building platform to form a 3D object.

SLA(Stereolithography) is a resin based technology, where the material is cured by the UV laser beam as per the slicing of the CAD file.The 3D Object is built from bottom to top with the supports created for overhangs and cavities, and later manually removed

LS(Selective Laser Sintering) is a laser based technology, where the laser beam sinters the plastic powdered material layer by layer each time lowering the powder bed.No support structures are formed,since the powder is self-supporting.

DMLS(Direct Metal Laser Sintering) is a laser based technology, where laser beam sinters the solid metal powdered material layer by layer each time lowering the powder bed. Due to high metal temperature ,support structures are formed to avoid wrapping of the part. After printing,heat treatment is mandatory for DMLS parts

Vacuum Casting is a copying technique by creating a silicon mold, and later PU material is poured in to the mold under vacuum environment to create high quality end-use parts. It is mostly used for small batch production.
