Abstract Scope |
Additive manufacturing (AM) has matured beyond limited use-cases in rapid prototyping into a process capable of competing with conventional manufacturing methods for production of end-use components. As such, many manufacturers are evaluating candidate products for redesign for AM (rDFAM), with interest in improving component performance, streamlining manufacturing, and reducing costs. Herein a bicycle stem is used as an exemplar case study of component redesign for AM. Design constraints, AM process selection, and material selection are considered. Generative design is used to optimize the component’s weight given the design constraints. An end-to-end manufacturing process chain is consequently developed and analyzed for viability, covering DFAM and post processing. Through this comprehensive case study, it is shown that significant weight savings, greater than 25% in the present case, can be achieved through the rDFAM process. Guidelines from the rDFAM process are generalized for application to further cases. |
