摘要： A system and method is disclosed for detecting anomalies in an additively manufactured part. An energy source generates a signal forming an optical beam for creating a melt pool in a layer of feedstock material being selectively fused to make a part in an additive manufacturing operation. A sensor is configured to receive a signal reflected from the melt pool. The reflected signal forms a thermal signal indicative of a temperature of the feedstock material at a known location on a layer of the feedstock material while the feedstock material is being fused at the known location. A controller receives and analyzes data relating to the received signal to determine if an anomaly exists at the known location.

摘要： Disclosed are flow-through electrode devices and techniques for making flow-through electrodes. In one aspect, a flow through electrode apparatus comprises one or more fiber layers. Each fiber layer comprises a plurality of fibers oriented to be orthogonal to a flow direction of a fluid. The plurality of fibers are configured to cause an inertial flow of the fluid around the plurality of fibers at a first flow rate of the fluid.
