72 In-situ characterisation of melt pool temperature in a commercial PBF-LB system
This paper provides a general methodology for calculating temperatures based on recorded measurements from a commercial melt pool monitoring system with accompanying data processing and visualization. A case is presented for Ti-6Al-4V processed by laser-based powder bed fusion. The results provide temperatures that closely match literature values and demonstrate the expected higher temperatures in thinner regions, coinciding with decreased conduction and shorter scan meanders of the laser path. Overall, the method and application suggest a promising outlook for the use of such melt pool monitoring systems in part validation to ensure safety and performance of produced components.
