Abstract
A method of fabricating a part by selectively melting powder is provided. The method includes: depositing a first layer of a first powder having a first element as its main element; depositing, on the first layer, a second layer of a second powder having a second element as its main element, which second element is different from the first element; and moving a first energy beam over the second layer, the energy delivered by the first beam serving to initiate an exothermic reaction between the first element and the second element, the energy given off by the exothermic reaction acting to locally melt together the first and second layers.
