Abstract Scope |
Diode Point Melting (DPM) is a novel additive manufacturing approach that can produce by focusing multiple diode laser sources into a single beam spot, offers an alternative approach to traditional laser powder bed fusion techniques. With this motivation, this work aims to determine optimum process parameters of DPM using 450 nm low wavelength multiple diode sources. In this study, Ti6Al4V powder used as a production material with different laser powers (19W and 38W), different hatch distance (50, 75, 100 and 125 μm) and different layer thickness (30, 60, 90 and 120 μm) and different speed (800, 1200, 1600 and 2000 mm/min) were considered as process parameters. The results showed that samples with density up-to 99.4% can be produced by using the optimum process parameters obtained. The results also revealed that DPM approach reveals the potential of a promising production method according to traditional additive manufacturing techniques. |
