Method for manufacturing metal objects using metal objects and disposable molds

摘要

A method of manufacturing a metal object is provided. These methods generally include adding a metal powder slurry to a sacrificial mold, such as a mold made by three-dimensional printing, and heating the slurry / mold mixture. The heating process consists of curing the slurry to create a green body in the mold, removing the binder and burning the mold and binder to create a brown body, sintering, and hot isostatic pressing. Pressing may be included. Metal products such as aircraft engine parts are also provided. [Selection] Figure 2
