Abstract Scope |
Diode Area Melting (DAM) presents an alternative approach to traditional Laser Powder Bed Fusion (LPBF) approaches, integrating multiple individually addressable low-power fibre-coupled diode lasers into a laser head, these traverse across a powder bed to melt powdered feedstock. DAM research to date has focused on using low-power 808nm lasers to process Ti6Al4V (Ti64) powder. This work focuses on using multiple short wavelength 450nm 3W lasers to process Ti64 feedstock. It was found that when processing Ti64, absorption was 11% higher using 450nm lasers when compared to using 808 nm lasers and 14% higher than 1064nm lasers. This work demonstrated the potential to use shorter wavelength lasers in DAM/LPBF for improved melting efficiency and also it aimed to examine the impact of 450nm diode lasers on Ti64 and generate a parameter map for this material. |
