Abstract: An information processing apparatus for controlling additive manufacturing of a powder bed method includes an acquirer that acquires roughness data indicating a roughness of a manufacturing surface after melting, and defect determiner that divides the manufacturing surface into small regions each having a predetermined size, and compares the roughness data with a predetermined threshold for each small region, thereby determining whether a defect exists in the small region. If an unmolten region is included in the small region, the defect determiner replaces data of the manufacturing surface in the unmolten region using data of the manufacturing surface in the small region, and determines whether a defect exists in the small region including the unmolten region. Also, the manufacturing defect detection method further includes a defect repair instructor that instructs remelting of a region that is determined by the defect determiner to have a defect.
