Abstract: Methods of making metal objects are provided. These methods generally involve adding a metal powder slurry into a sacrificial mold, such as a mold made by three dimensional printing, and heating the slurry/mold mixture. The heating steps may include curing the slurry to make a green part inside the mold, debinding to burn off the mold and binder to make a brown part, sintering, and hot isostatic pressing. Metal products, such as aircraft engine parts, are also provided.
