Abstract

An information processing apparatus includes: a defect candidate specifying unit (72) configured to specify a plurality of defect candidates positioned at substantially the same positions in a plurality of layers adjacent to each other in a stacking direction; a defect detection unit (73) configured to detect a defect remaining in a manufactured object based on a size of the plurality of defect candidates positioned at the substantially same positions and specified in the plurality of layers in the stacking direction and a size of each of the plurality of defect candidates in the layer, and to determine the defect as any one of a first defect which is not allowed to remain in the manufactured object and a second defect which is allowed to remain in the manufactured object based on a maximum length of the defect; and a display control unit (74) configured to create a visualized image obtained by visualizing defect information including at least one of the first defect and the second defect and to perform control such that the visualized image is displayable on a display unit (90) during powder bed fusion additive manufacturing.
