Abstract Error#1: Laser beam speed is increasing as Alpha (α) increases (1) V0 = ω*R ; Beam Surface speed at the center(2) h = R*tan(α) ; Travel distance on work surface(3) α =ω*t ; Test values Derivatives errors (more errors) derived from Error#1:Modulation shift sintering coordinates as modulation “assumes” constant speed. F-theta lens…
Abstract Selective Laser Sintering (SLS) is an additive manufacturing process in which a powdered material is heated below its melting point and sintered using a high intensity laser. The most useful application of this technology pertains to Direct Metal Laser Sintering (DMLS), which applies SLS technology to the production of strong, complex, metal 3D parts.…
