Abstract
An additive manufacturing system includes an energy source and a material delivery device. The energy source is configured to direct an energy beam toward a component to form a melt pool. The material delivery device is configured to feed a wire toward the melt pool to deposit material on the component. In some examples, the material delivery device is configured to discharge a current to the wire to disengage the wire from the melt pool. In some examples, the material delivery device is configured to measure an arc voltage between the wire and the component.
Claims19
An additive manufacturing system comprising:
- an energy source configured to direct an energy beam toward a component to form a melt pool;
- and
- a material delivery device comprising:
- a feed actuator configured to feed a wire toward the melt pool;
- and
- control circuitry comprising a measurement circuit configured to, in response to a control signal indicating measurement of an arc voltage:
- discharge a current to the wire to generate an arc from the wire to the component;
- and
- measure the arc voltage between the wire and the component corresponding to a distance between the wire and the melt pool.
6 more elements
A method comprising:
- controlling, by a computing device, a material delivery device to:
- discharge a current to a wire to generate an arc from the wire to a component:
- measure an arc voltage between the wire and the component corresponding to a distance between the wire and the component;
- and
- feed the wire toward a portion of the component;
- and
- controlling, by the computing device, an energy source to direct an energy beam toward the portion of the component to form a melt pool.
