Laser-based powder bed additive manufacturing was used to fabricate mechanical test specimens using Type 304L stainless steel using identical processing parameters. Three-point bend specimens were built vertically using a common scan strategy at plate locations with different surrounding heat sink conditions. Fracture toughness properties of as-built and hydrogen-precharged specimens were measured as a function of build location. The purpose was to develop an understanding of the effects of additive manufacturing (AM) build parameters and table conditions on fracture toughness and hydrogen compatibility. The results show that the fracture toughness properties of the as-built steels fell into two ranges: higher toughness...
