摘要
A three-dimensional powder bed fusion additive manufacturing apparatus includes: a base plate; a Z drive mechanism configured to move the base plate in a vertical direction; a powder supplier configured to supply a powder sample onto the base plate to laminate a powder layer; an electron gun configured to generate a beam to be irradiated to the powder layer; a controller configured to control the Z drive mechanism, the powder supplier, and the electron gun to irradiate the beam to a powder bed that is an uppermost layer of the powder layer and perform melting on a two-dimensionally shaped region in which a shaped model is sliced by one layer to shape a three-dimensionally shaped object; and two segment detectors configured to detect a state of the powder bed.
