Abstract: An additive manufacturing development method includes predicting a defect that occurs in a product based on a combination of a plurality of design data and a plurality of manufacturing conditions, collecting defect detection data for defect detection by monitoring the product during manufacturing in accordance with the combination of the plurality of design data and the plurality of manufacturing conditions, and generating a process map in which the plurality of manufacturing conditions are plotted using the predicted defect and the collected defect detection data. The method further includes collecting defect repair data for defect repair by monitoring the product during manufacturing and repairing a defect detected from the product, and storing the defect and the defect repair data in association with each other using the defect repair data and a repair result.

Abstract: This invention is directed to a method of efficiently improving a relative density of a shaped object using an evaluation criterion having a higher correlation with a density of an object to be shaped. The method according to this invention includes acquiring three-dimensional point group data of a surface of a shaping object, calculating at least one of three-dimensional surface texture parameters extended to a plane region using the three-dimensional point group data, and evaluating a quality of the object to be shaped using the at least one of the three-dimensional surface texture parameters.
