Abstract
An object of the present invention is to provide a method for manufacturing a metal printed object that can reduce the generation of sputters, and the present invention provides a method for manufacturing a metal printed object in which, in the presence of a shielding gas supplied around metal powder in a chamber, heat is supplied to the metal powder using energy rays to form a metal layer and laminate 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 is 1.30×10−3 g/cm3 or less.
Claims4
A method for manufacturing a metal printed object in which, in the presence of a shielding gas supplied around metal powder in a chamber, heat is supplied to the metal powder using energy rays to form a metal layer and the metal layer is laminated,
- wherein the mass per unit volume of the shielding gas at a temperature of 25° C. and a pressure of 0.1 MPa is 0.448×10−3 g/cm3 or less, and
- wherein a gauge pressure of the shielding gas in the chamber is 0 to 0.1 MPa, and
- wherein the shield gas contains 1% by volume or less of oxygen with respect to 100% by volume of the shielding gas.
