THREE-DIMENSIONAL LAMINATING AND SHAPING APPARATUS, CONTROL METHOD OF THREE-DIMENSIONAL LAMINATING AND SHAPING APPARATUS, AND CONTROL PROGRAM OF THREE-DIMENSIONAL LAMINATING AND SHAPING APPARATUS

摘要

A metal laminated and shaped object is shaped by optical shaping. A three-dimensional laminating and shaping apparatus includes a shaping stage as a place where a metal laminated and shaped object is shaped, a moving unit that moves the shaping stage, a supplier that supplies metal powder particles in a layer on a surface of the shaping stage, and a light irradiator that irradiates, with a laser beam, powder particles at a predetermined position among the powder particles supplied in the layer on the surface of the shaping stages. The light irradiator includes a laser diode that emits the laser beam, and an electromechanical mirror that reflects the laser beam and irradiates, with the laser beam, the metal powder particles at the predetermined position among the metal powder particles supplied in the layer on the surface of the shaping stage. The supplier supplies metal powder particles having a particle size of not more than 50 μm. The moving unit moves the shaping stage by one layer in a direction away from the light irradiator in accordance with the particle size.
