Abstract

Thermal properties of additive manufacturing (AM) solids and precursor materials are important factors for build process and part performance. However, measured thermal properties are not well documented, despite being used extensively in AM modeling and simulation. NIST and the University of Louisville are developing the measurement science for AM material thermal properties. New measurement methods, sample preparation techniques, and results analyses are demonstrated for laser flash (LF) thermal diffusivity measurements on metal AM solids and powders. Due to the complexity of these materials, new sample fabrication methods are required and demonstrated. Results from LF measurements are presented and compared.
