  • Publication number: 20170364058
    Abstract: A method of producing a heat exchanger includes designing the heat exchanger to include a wall with a target thickness. A model is created relating process parameters to geometry of a single track melt pool and relating the single track melt pool geometry to a heat exchanger wall thickness. At least one variable process parameter is defined. The model, heat exchanger wall target thickness, and variable process parameters are used to identify a set of process parameters to produce the heat exchanger wall target thickness. The melt pool geometry is predicted based on the model and process parameters. The heat exchanger wall target thickness is predicted based on the melt pool geometry. The process parameters that will produce the heat exchanger wall target thickness are identified. The additive manufacturing process is controlled based upon the identified set of process parameters to create the heat exchanger wall target thickness.

  • Publication number: 20170197248
    Abstract: A method of making an article is disclosed in which a fusible material is fused with an energy beam applied to the fusible material at a build location with a scanning pattern comprising a plurality of parallel lines terminating at the contoured edge. An energy beam is also applied with a vector scanning pattern at the build location along the contoured edge to liquefy and re-solidify material at the build location along the contoured edge. The method also includes controlling vector scanning energy beam intensity, vector scanning energy beam scanning speed, vector scanning energy beam focus depth, or any combination thereof as a function of an angle between the plurality of parallel lines and the vector along the contoured edge.

  • Publication number: 20170113253
    Abstract: A method includes issuing a state change fluid into an internal passage of an additively manufactured article and 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. The method can also include causing the state change fluid to change back from the second state to the first state and flushing the state change fluid from the internal passage to remove residual powder from the additively manufactured article.
