Abstract
A modeling method for a workpiece and the workpiece are provided. When the workpiece, at least a part of the workpiece has a hollow region and two or more openings linking an inside and the outside of the hollow region, is additively manufactured, a temporary closure to block at least one of the two or more openings of the hollow region is manufactured at a same time as laminating of a wall section of the hollow region. A peripheral edge of the temporary closure joined to the wall section, and the temporary closure has a flow hole allowing a fluid to flow in or out of the hollow region, then the temporary closure is removed after the fluid has flowed in or out.
