Development of an integrated design methodology model for quality and throughput of Additive Manufacturing processes

Abstract

Additive manufacturing (AM) has risen to be a substantial part of modern manufacturing due to its unique capabilities and has already been fondly adopted in various fields especially in the aerospace. In order to fully harness the benefits of this revolutionary manufacturing technology, this article aims to develop a practical integrated design methodology that can be used to enhance quality and throughput of AM processes. In doing so, investigation were conducted to examine an AM aero-based component through design tools that allow designers to consider an integrated process chain, from component design to pre-processing, manufacturing (laser bed fusion building), post-processing and finished part. The developed design model integrated with decision tools will assist the design experts in developing new knowledge that looks beyond the familiar Design for Additive Manufacturing (DfAM) rather to Design towards product Certification (DoC). In addition, this will serve as an effective design guidance that can inform proper design planning and optimization in aerospace industry production.
