Traditional SLS/SLM 3D Printing Errors
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.
