THREE-DIMENSIONAL MOLDING APPARATUS, DISCHARGE UNIT, AND METHOD FOR MANUFACTURING THREE-DIMENSIONAL MOLDING OBJECT

摘要

PROBLEM TO BE SOLVED: To improve productivity in a three-dimensional molding apparatus using a small-diameter nozzle.;SOLUTION: A three-dimensional molding apparatus has: a first discharge unit having a first material melting part that melts a material to form a molding material, and a first nozzle that communicates with the first material melting part through a first communication hole and discharges the molding material supplied from the first material melting part; a second discharge unit having a second material melting part that melts the material to form a molding material, and a second nozzle that communicates with the second material melting part through a second communication hole and discharges the molding material supplied from the second material melting part; and a control unit that controls the first discharge unit and the second discharge unit to mold a three-dimensional object. A nozzle diameter of the first nozzle is smaller than a nozzle diameter of the second nozzle. The control unit controls the first discharge unit and the second discharge unit so that the pressure of the molding material in the first communication hole is greater than the pressure of the molding material in the second communication hole when molding the three-dimensional molding object.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2020,JPO&INPIT
