Abstract: A method for additively manufacturing a component includes receiving, via an additive manufacturing system, a geometry of the component and melting and fusing, via an energy beam of the additive manufacturing system, material layer by layer atop a build platform according to the geometry so as to build up a plurality of layers that form the component. The method also includes determining a surface area change from one of the plurality of layers to the next based on the geometry. Further, the method includes temporarily discontinuing melting and fusing of the material by the energy beam between building of one or more of the plurality of layers so as to provide a delay after building one or more of the plurality of layers when the surface area change is above a predetermined threshold. As such, the delay allows for one or more previously built layers to at least partially cool so as to eliminate and/or reduce build failures from occurring in the final component.
