Abstract

In recent years, there has been a paradigm shift in the application of Additive Manufacturing (AM) processes as a low volume production system. Improved capabilities of several metal-based processes have made AM, a viable method to produce complex biomedical and aerospace parts. Often, such high performance parts are made of expensive alloys and the solid freeform aspect of AM significantly reduces tooling, material cost and time. However, it is critical to study the economics of individual AM processes to better understand its relative cost effectiveness. In this study, three unique approaches: EBM (additive), CNC-RP (subtractive) and a hybrid process are studied. Part 'geometry-based' analysis in terms of part volume-convex hull volume ratio, aspect ratio, etc. is performed to correlate it with cost-performance of the processes. Results from this study will aid in the optimization of AM process selection and 'feature-selection' for individual processes in an integrated system.
