Abstract: Additive manufacturing techniques are used to achieve customized preforms for repair or manufacture of turbomachinery. A method of modifying a section of a product includes forming, a preform set to fit the section. A base material is selected with properties desired for the modification of the section. A binder is selected that vaporizes at a temperature below a melting point of the base material. The preform set is built by the selective application of the binder to the base material to achieve design dimensions of the section when the preform is joined to the section. The section is prepared for effecting the extent of modification and the preform is positioned on the section. The section and the preform are heated to substantially eliminate the binder from the preform and then thermally processed to harden the preform and to bond the preform to the section.

Abstract: Methods and build materials are provided for producing articles with additive manufacturing processes. The methods comprise providing a build material comprising a powder mixture of about 95.0 wt. % to about 99.95 wt. % metallic powder and about 0.05 wt. % to about 5.0 wt. % graphene powder and performing an additive manufacturing process to produce the article from the build material. The graphene powder comprises nanoplatelets having between 1 and 30 layers of graphene.
