Abstract
Methods for anomaly detection in additive manufacture using meltpool monitoring are disclosed. A method includes obtaining a process model representative of an object to be generated through additive manufacture. The method also includes generating, based on the process model and using a hybrid machine-learning model, an instruction for generating the object through additive manufacture. Another method includes generating a layer of an object, and taking a reading relative to the generation of the layer. The other method also includes updating, based on the reading and using a hybrid machine-learning model, a process model, the process model representative of the object. The other method also includes generating, based on the updated process model and using the hybrid machine-learning model, an instruction for generating a subsequent layer of the object through additive manufacture. Related systems and devices are also disclosed.
