Abstract
A component includes a component segment, a foundation built on the component segment, and a plurality of distortion mitigation structures built on the component segment. The component segment, foundation, and the plurality of distortion mitigation structures are built with a first additive manufacturing (AM) technique. The component further includes a boss built on the foundation using a second AM technique. The plurality of distortion mitigation structures are configured to radiate away from the foundation and to dissipate heat generated on the foundation when the boss is built using the second AM technique.
Claims20
A component, comprising:
- a component segment, a foundation built on the component segment, and a plurality of distortion mitigation structures built on the component segment, wherein the component segment, foundation, and the plurality of distortion mitigation structures are built with a first additive manufacturing (AM) technique;
- and
- a boss built on the foundation using a second AM technique;
- wherein the plurality of distortion mitigation structures are configured to radiate away from the foundation and to dissipate heat generated on the foundation when the boss is built using the second AM technique.
A method of making a component, comprising:
- building, using a first additive manufacturing (AM) technique, a component segment, including an integral foundation for a boss and a plurality of distortion mitigation features on a build platform of a first AM device;
- removing the component segment from the first AM device;
- moving the component segment to a second AM device;
- positioning an energy/powder head of a second AM device over the integral foundation using the integral foundation as a location datum;
- building, using the energy/powder head of the second AM device and a second AM technique, the boss on top of the integral foundation to build a completed component;
- removing the completed component from the second AM device.
