Abstract: Friction-based additive manufacturing (FBAM) has gained popularity in recent years, with applications in a wide range of domains. FBAM process is highly suitable for aluminium alloys. Due to the high strength to weight property, aluminium alloy has significant applications in industry such as aerospace, marine and automotive domains. A structural model illustrating the interrelationship of factors could be developed to improve the effectiveness of FBAM. In this regard, this article describes the development of a structural model for FBAM using interpretive structural modelling (ISM) approach. The development of a structural model and MICMAC analysis revealed key influencing factors. According to the derived model, the factors 'no usage of consumable electrode', 'no problems with hot cracking, porosity', and 'no post processing' are dominant. The implications for additive manufacturing practitioners are being highlighted.

Keywords: additive manufacturing; friction-based additive manufacturing; FBAM; interpretive structural modelling; ISM; modelling; MICMAC analysis.
