Selective sintering additive manufacturing method

A method for producing a component layer-by-layer. The method includes the steps of: depositing particulate material to form a layer of particulate material having a first area over a build platform; applying at least one exothermic material over the build platform so that a selected portion of the...

Beschreibung
Zusammenfassung:	A method for producing a component layer-by-layer. The method includes the steps of: depositing particulate material to form a layer of particulate material having a first area over a build platform; applying at least one exothermic material over the build platform so that a selected portion of the first area is uniformly coated with the exothermic material; selectively sintering a second area of the layer smaller than the selected portion of first area, using an application of radiant energy to trigger an exothermic reaction in the at least one exothermic material, in a specific pattern that defines the geometry of a cross-sectional layer of the component; and repeating the steps of depositing, applying, and sintering for a plurality of layers until the component is complete.
