Abstract

A method of manufacturing an object is disclosed. In some aspects, the method includes selectively heating an initial layer of a composition, including elements of a granular material coated with a metallic material. The method further includes selectively heating an additional layer of the composition, disposed in contact with the initial layer, the selective heating of each respective layer to the threshold temperature actuating an exothermic reaction between the elements of the granular material and the metallic material coating associated therewith to form a molten portion of the respective layer, with turbulence in the molten portion of the respective layer disrupting oxidation of the molten granular material and promoting formation of an intermetallic compound in the molten portion of the respective layer upon cooling thereof below the threshold temperature, and with the portions of the respective layers combining to form the object.
