In laser powder bed fusion (LPBF) additive manufacturing, the thermal diffusivity of the powder bed is a very important factor. The thermal characteristics of the powder bed have a significant impact on the mechanical characteristics of the products created by LPBF. This work uses a laser flash three-layered analysis in the DLF1600 instrument, which has a special powder cell to enclose the powdered sample, to assess the thermal diffusivity of metallic powder, nickel-based super alloy Inconel718 (IN718). Measurements were performed at different temperatures. Test data were also analyzed in the R software for further verification.
