Recent development of nickel superalloys for additive manufacturing has shown to be challenging due to the susceptibility to micro cracking in as build microstructure. Significant effort has gone into optimizing build parameters for these hard to process alloys. To reduce the parameter development cycle for challenging materials, GE Research developed and continue to enhance a framework that utilizes probabilistic machine learning (ML), intelligent sampling and optimization protocols, coupled with high-throughput printing, characterization, and in-situ monitoring systems to dramatically accelerate the developmental process. A new protocol was developed by leveraging machine learning algorithm. In this presentation, the framework along with demonstration of the use of machine learning method to guide parameter development for additive manufacturing will be given.
