Document Type and Number:
WIPO Patent Application WO/2022/163110
Kind Code:
A1
Abstract:
Provided is a method which is for manufacturing a porous metal body and by which a porous metal body, which has a suppressed variation in thickness even when a molding plate having a relatively small thickness is used multiple times, can be manufactured. This method for manufacturing a porous metal body involves performing a process multiple times, the process including: a depositing step for depositing metal powders in a dry manner on a molding plate 100, which is made of carbon and has a thickness of at most 30 mm and an area of a surface, on which metal powders are deposited, of at least 36 cm2; and a sintering step for sintering the metal powders on the molding plate 100, wherein the plurality of the processes are performed using the same molding plate 100, and at least one process among the plurality of the processes further includes, between the depositing step and the sintering step, a thickness adjusting step for adjusting the thickness of the metal powder-deposited layer on the molding plate 100 while making a surface 105 of the molding plate 100 have a flat surface shape.
