Abstract: 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.

Abstract: The present disclosure generally relates to additive manufacturing systems and methods involving a mechanism for feeding in a desired amount of fresh recoater blade. This can be accomplished by, for example, spooling the fresh blade material from a spool. This helps prevent work stoppage when a portion of a recoater blade becomes damaged. As such, the present disclosure also relates to a system and method for detecting whether a recoater blade is damaged, and if there is damage, then causing a fresh blade portion to be fed in.
