Abstract
A self-monitoring additive manufacturing system and method of operation utilizes a surface imaging monitor to image a surface of a slice of a workpiece for storage and processing of the image to detect surface anomalies. The monitoring may operate in real time and in unison with an energy gun of the system for correction of the anomalies in real-time by re-melting of the anomaly.
Claims20
An additive manufacturing system comprising:
- a layer of raw material;
- an energy gun for melting at least a portion of the layer and thereby forming at least in part a slice of a workpiece;
- and
- a surface monitor for detecting surface anomalies of the portion after solidification.
1 more element
A method of operating an additive manufacturing system comprising the steps of:
- forming at least a portion of a slice of a workpiece;
- taking an image of a surface of at least the portion of the slice with a surface monitor;
- and
- identifying an anomaly of the surface through the image.
