Abstract
Systems and methods for additive manufacturing support removal of an additive manufactured component are provided. The method includes additively manufacturing a built component including at least one support having a thickness, and gaseous carburizing the built component and the at least one support to form a carburized component and at least one carburized support. Each of the carburized component and the at least one carburized support have a carburization layer with a predefined depth. The method includes removing the carburization layer to form the component devoid of the at least one carburized support.
Claims19
A method for additive manufacturing support removal of an additive manufactured component, comprising:
- additively manufacturing a built component including at least one support having a thickness;
- gaseous carburizing the built component and the at least one support to form a carburized component and at least one carburized support, each of the carburized component and the at least one carburized support having a carburization layer with a predefined depth;
- and
- removing the carburization layer to form the component devoid of the at least one carburized support.
A system for additive manufacturing support removal and for surface finish enhancement of a component, comprising:
- a source of an additively manufactured built component that includes at least one support;
- a gaseous carburization system that carburizes the built component and the at least one support to form a carburized component and at least one carburized support, each of the carburized component and the at least one carburized support having a carburization layer with a predefined depth;
- and
- an etch system that removes the carburization layer to form the component devoid of the at least one carburized support.
The system of claim 12, wherein the cathode electrode is a conformal electrode that is insertable into at least one of the carburized component and the at least one carburized support prior to the etching.
A method for surface finish enhancement of a manufactured component, comprising:
- providing a component that is composed of at least one corrosion resistant element, the component including at least one internal passage;
- gaseous carburizing the component to form a carburized component, the carburized component having a carburization layer with a predefined depth;
- and
- etching the carburized component in an anodic etch system to remove the carburization layer to enhance a surface finish of the component.
