Abstract: Devices, systems, and methods for selectively sintering a powder layer in additive manufacturing processes to achieve a desired heat conductivity are disclosed. A method includes distributing a powder layer in a build chamber, selectively sintering the powder layer to form a plurality of sintered areas and a plurality of non-sintered areas based on a thermal model, and melting a subset of the plurality of sintered areas.
