An optimisation framework for designs for additive manufacturing combining design, manufacturing and post-processing

Purpose The purpose of this paper is to present a Design for Additive Manufacturing (DfAM) methodology that connects several methods, from geometrical design post-process selection, into common optimisation framework. Design/methodology/approach A formulated and tested in case study. outcome the study analysed by comparing obtained results with alternative designs achieved using other methods. process potential method be used different settings are also discussed. Finally, work concluded stating main contribution highlighting where further research needed. Findings proposed implemented novel framework which applied physical component structural aircraft part was designed minimise weight while respecting static fatigue load cases. An addition goal manufacturing cost. Designs optimised two AM machines (EOS M400 Arcam Q20+), without post-processing (centrifugal finishing) considered. show significant reduction both cost compared one manufactured geometry more conventional methods milled aluminium. Originality/value allows holistic components considering manufacturability, functionality. Within same framework, setups can automatically evaluated any additional manual work.
