| Abstract Scope |
Metal additive manufacturing is a rapidly growing technology that offers many potential benefits to the automotive industry, such as functional prototyping, more design flexibility leading to light weighting and/or improvement in part performance, and the potential to reduce the cost and time associated with tooling for specific low volume part designs. Current challenges for implementing this technology for automotive manufacturing include expanding availability of automotive grade alloys, increasing throughput of machines, and controlling part quality, properties, and repeatability. This talk will focus on the development of GM custom aluminum and steel alloys for laser powder bed fusion systems. These alloys are designed to be low cost, tailored for AM processing, and applicable to a variety of vehicle applications. Microstructures and mechanical properties of samples built with these alloys will be discussed. The approach of minimizing post-processing to improve throughput will also be discussed. |
