Title:
3D laminated modeling device, 3D laminated modeling device control method and 3D laminated modeling device control program
Document Type and Number:
Japanese Patent JP6357540
Kind Code:
B2
Abstract:
A high-precision three-dimensional laminated and shaped object is shaped. A three-dimensional laminating and shaping apparatus includes a material ejector that ejects a material of the three-dimensional laminated and shaped object onto a shaping table. The three-dimensional laminating and shaping apparatus also includes a light beam irradiator that irradiates the ejected material with a light beam. Furthermore, the three-dimensional laminating and shaping apparatus includes a light beam path controller that is arranged on a light beam path of the light beam, detects a material focus position on the shaping table, and controls the light beam path of the light beam based on the detected material focus position. The light beam path controller aligns the light beam focus position with respect to the material focus position.
