Using finite element analysis to influence the infill design of fused deposition modelled parts

Abstract: Additive manufacturing (AM) has and continues to experience considerable market and technological growth with many forecasting a tripling in market value over the next decade. One of the primary drivers for this growth is the increased freedom afforded to the design of both the external form and internal structure of fabricated parts. This freedom presents greater opportunities in optimising a parts mechanical properties, (such as strength, stiffness and mass), which in turn leads to enhanced performance whils… Show more

“…According to this refinement technique, the objective was to subdivide infill design in such a way that continuous printing constraint is satisfied while increasing the strength of the part. In hindsight, like the work in [12,17], we suspect it could bring benefits to place the material as infill along the stress field direction during the refinement. Some of the ideas that we will address concerning the present refinement methodology as future works are: Adding the capability to align the infill along the stress field by moving the nodes of the elements of infill design.…”

“…This proved that placing material in the direction of principal stress truly could help to reduce material usage and increase the stiffness of the part. In another study, the same authors [17] have proposed a method using the results of finite element analysis (FEA) to influence the internal geometry of components. A rectangular part undergoing different loading scenarios has been studied.…”

“…For example, systems from Mueller et al [19] and Peng et al [22] approximate the objects' surface, by printing a wireframe version of the geometry, but this reduces fdelity and is therefore only applicable for certain kinds of rapid prototyping. If object detail is important, material consumption can be reduced by optimizing the required infll to support all exterior walls of the object [14], or to optimize only for expected loads [11,26]. Our system follows a diferent approach to reduce infll and can be applied in conjunction with infll optimization for even greater material savings.…”
