Title:
METHOD FOR MANUFACTURING METAL MODELED OBJECT
Document Type and Number:
WIPO Patent Application WO/2019/203275
Kind Code:
A1
Abstract:
In order to provide a method for manufacturing a metal modeled object, whereby manufacturing time can be reduced by a convenient method without the need for large-scale modification of a manufacturing apparatus, the present invention provides a method for manufacturing a metal modeled object, comprising supplying heat to a metal powder on a base plate using energy rays in the presence of a shielding gas supplied to the periphery of the metal powder, modeling a metal layer on the base plate, and sequentially layering the metal layer, wherein the mass per unit volume of the shielding gas at a temperature of 25°C and a pressure of 0.1 MPa during modeling of a first metal layer adjacent to the base plate is 1.00 × 10-4 g/cm3 to 1.3 × 10-3 g/cm3.
