- - - - The plastic filament is melted and extruded through the Extruder and the part will be slowly built layer by layer. Extra supports are also included by the system if there is an overhang in the design.

    - - The powder is heated to just below its melting point. The laser then draws one cross section of the part to sinter the powder particles. Un-sintered powder is used for support the next layer, which is distributed, leveled, and sintered.
      - The platform is raised to allow removal of the part from the powder after cooling. The excess powder is then being brushed off.

    - - generating a ultraviolet laser beam that solidifies focused surface areas of the photopolymer. The laser beam traces a cross-section of the part pattern on the surface of the resin. The platform is then slowly lowered as the part is being built layer by layer.
