Additive Manufacturing in the Mobility Industry: Vol. 3

Success in metal AM relies on the optimization of a large set of process parameters to achieve materials whose properties and performance meet design and safety requirements. Despite continuous process improvements over the years, the quality of AM parts remains a major concern for manufacturers. Today, researchers are starting to move from discrete, geometry-dependent build parameters to continuously variable or dynamically changing parameters that are geometry- and scan-path aware. This approach has become known as “feedforward control.” This chapter discusses the origins of feedforward control, its early implementations in AM, the current state of the art, and a path forward to its broader adoption.
