Title: 3D ADDITIVE MANUFACTURING SYSTEM, 3D ADDITIVE MANUFACTURING METHOD, ADDITIVE MANUFACTURING CONTROL DEVICE, AND CONTROL METHOD AND CONTROL PROGRAM FOR ADDITIVE MANUFACTURING CONTROL DEVICE
Abstract:
The system of the present invention is a 3D additive manufacturing system that prevents, in advance, a squeegee blade from becoming caught on a manufactured object obtained by additive manufacturing. This 3D additive manufacturing system is equipped with: an additive manufacturing unit that is provided with a squeegee blade for blanketing a layering material upon the top layer of an additively manufactured object and an irradiating unit for irradiating the layering material, and manufactures each layer of the additively manufactured object as a collection of cell regions; and an additive manufacturing controlling unit that controls the additive manufacturing unit such that the scanning direction in which the irradiating unit irradiates the layering material within a cell region changes during additive manufacturing relative to the movement direction of the squeegee blade.
