Effectiveness of virtual models in design for additive manufacturing: a laser sintering case study

Purpose – Additive Manufacturing (AM) technologies have conventionally focused on producing prototypes. However, recent trends show that AM is being increasingly used for production parts. With this shift from prototypes to production parts, there is a need to determine whether established engineering design techniques can be applied to AM processes, particularly techniques characteristic of the final implementation phase such as virtual (mathematical) modeling, or whether AM process‐specific adjustments must be made.Design/methodology/approach – The effectiveness of applying virtual models to design problems utilizing AM processes was addressed using two approaches in this research. Literature was first reviewed to determine the current focus of the AM industry on virtual modeling, both analytical and numerical, and its implementation. Second, experiments were conducted to validate virtual models applied to fastener mechanism designs manufactured using laser sintering (LS).Findings – Limited research has...
