Abstract:
A powder material as the raw material of a three-dimensional laminated and shaped object is accurately evaluated. This invention provides an evaluation apparatus of a powder material as a raw material of a three-dimensional laminated and shaped object, including a calculator that calculates, using powder constitution data concerning particles constituting the powder material, a volume of a closed space formed by the plurality of particles in the powder material, and an evaluator that evaluates the powder material by comparing the volume of the closed space calculated by the calculator with a predetermined threshold.
