Abstract

Exemplary embodiments are disclosed of powder bed recoaters including non-contact powder redistributors. Also disclosed are exemplary embodiments of powder bed additive manufacturing systems including non-contact powder redistributors and methods for recoating powder beds. In an exemplary embodiment, a method comprises applying powder in a pattern along a top surface of a powder bed such that the applied powder covers only one or more portions, and not the entirety, of the powder bed. The method further comprises redistributing the powder in the pattern to flatten or level the powder bed without physically contacting the powder bed.
