Abstract Scope With growing interest in electrification from clean energy technologies, such as wind power, and the use of pure electric powertrains in various applications, the demand for next-generation, high-performance magnetic materials has risen significantly. Electrical machine design for these applications is facing challenges in terms of meeting very demanding metrics for power densities and conversion efficiencies, thereby motivating the exploration of advanced materials and manufacturing for the next generation of lightweight ultra-efficient electric machines. In this work, the state of the art in additive manufacturability and performance characteristics of soft magnetic materials for electric machines will be summarized and presented. The prospects of soft magnetic materials selection in terms of price, printability, weight, and performance of the electrical machines will also be discussed. We will highlight the current status of AM of large electrical machines, additive manufacturing process selection guidelines, hybrid printing technologies, and the associated opportunities and challenges.
