Smoothing additive manufactured parts using ns-pulsed laser radiation

Abstract It is well known that the surface topography of a part can affect its mechanical performance, which typical in additive manufacturing. In this context, we report about modification manufactured components made Titanium 64 (Ti64) and Scalmalloy ® , using pulsed laser, with aim reducing their roughness. our experiments, nanosecond-pulsed infrared laser source variable pulse durations between 8 200 ns was applied. The impact varying large number parameters on quality smoothed areas investigated. results demonstrated reduction roughness Sa by more than 80% for 65% samples. This allows to extend applicability beyond current state art break new ground application various industrial applications such as aerospace.
