Abstract: A method includes placing an additively manufactured article having one or more internal channels in a non-reactive liquid to remove remainder powder from within the one or more internal channels, wherein the non-reactive liquid is a gas at room temperature and/or pressure. Placing the additively manufactured article in the non-reactive liquid includes can include placing the additively manufactured article in liquid nitrogen.

Abstract: A support structure for an additive manufacturing system includes a support body with a support body material and an interface disposed on the support body with an interface material. The interface material has a ductile-to-brittle transition temperature that is higher than the ductile-to-brittle temperature of the support body material for selectively fracturing the interface material to separate an additively manufactured article from the support body.
