Fused Deposition Modeling (FDM) is a non-laser based RP process, wherein filaments of heated thermoplastic material are extruded from a tip which moves in the X Y Plane. A fine filament of molten material is extruded from the nozzle & it deposits on the platform, which moves in the Z direction. The platform is maintained at a lower temperature so that the molten material immediately adheres & solidifies to the pervious layer.

Supports are built wherever necessary of a soluble material, which is subsequently dissolved after part completion, by dipping the part in an ultra sonic water tank.
