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. F-theta lens … Continue reading Traditional SLS/SLM 3D Printing Errors
