Japanese Patent JP7471214
Kind Code:
B2
Abstract:
The present invention relates to an apparatus, method, and reference sample for searching for molding conditions of an additive manufacturing apparatus 100 based on a powder bed fusion method, and provides a search apparatus 200, a search method, and a reference sample that are remarkably more efficient and accurate than conventional counterparts.The reference sample for searching for the molding conditions is shaped so that it has a surface having aggregated punched holes formed by straight lines and curved lines involved in a fill region of a molding region (in-skin), a region for forming an overhang (down-skin), and a region for forming an outermost surface in the direction of molding height (up-skin). Slice data of the reference sample has at least two independent regions in an optional layer at a center in a lamination direction, and includes a small region and a large region. The small region has a width of 1 mm or less and is cut off from the outer edge of the reference sample. The large region is formed by a portion other than the small region.
