    Abstract: A method of manufacturing a component susceptible to multiple failure modes includes generating a stereolithography file including a geometry of the component. The geometry of the stereolithography file is divided into a plurality of layers. Each of the layers includes a first portion and a second portion of the component. Energy from an energy source is applied to a powdered material such that the powdered material fuses to form the first portion and the second portion of each of the plurality of layers. Applying energy from the energy source to form the first portion of the plurality of layers includes operating the energy source with a first set of parameters and applying energy from the energy source to form the second portion of the plurality of layers includes operating the energy source with a second set of parameters. The first set and second set of parameters are different.

    Abstract: A method for making a heat exchanger assembly is described, involving generating a digital model of a heat exchanger assembly that comprises a heat exchanger core within a housing. The digital model is inputted into an additive manufacturing apparatus or system comprising an energy source. The additive manufacturing apparatus applies energy from the energy source to successively applied incremental quantities of a metal powder, which fuses the powder to form incremental portions of the heat exchanger core and housing according to the digital model. Unfused or partially fused metal powder is enclosed in a first region of the heat exchanger assembly between the heat exchanger core and the housing.

    Abstract: A method including filling an internal passage of an additively manufactured (AM) article with a state change fluid, causing the state change fluid to change from a first state having a first viscosity to a second state that is either solid or has a second viscosity that is higher than the first viscosity within the internal passage, causing the state change fluid to change back from the second state to the first state, removing residual powder from the additively manufactured article by flushing the state change fluid from the internal passage, measuring electrical impedance of a piezoelectric wafer connected to the additively manufactured article, and determining that more than a threshold amount of residual powder remains within the AM article based on the measured electrical impendence of the additively manufactured article being outside of a selected range from an expected impendence value.
