review · International Journal for Simulation and Multidisciplinary Design Optimization
This paper reviews the integration of topology optimisation and additive manufacturing. Topology optimisation is a method used to find the most efficient material distribution in a structure to maximise stiffness, often resulting in intricate designs. Traditional manufacturing struggles with these complex geometries, but additive manufacturing, or 3D printing, offers significant advantages by enabling their direct production. The combination of these two technologies provides designers with considerable creative flexibility. Advances in additive manufacturing resolution are helping to bridge the gap between optimised designs and their practical product applications. The review aims to identify key research areas, outline relevant topology optimisation methods, and survey various scientific and industrial applications of this integrated approach.
This research is important because it explores how advanced design methods can be combined with modern manufacturing techniques. This integration allows for the creation of lighter, stronger, and more efficient components that were previously impossible to produce, benefiting various industries.
This work is relevant for industries seeking to produce complex, high-performance components. It could enable the creation of optimised parts for sectors like aerospace, automotive, or medical devices, where material efficiency and intricate designs are critical. The abstract indicates a focus on existing scientific and industry applications, suggesting this is applied research with potential for near-term industrial adoption in component manufacturing.

Topology optimization is widely recognized for its ability to determine the best distribution of material in a structure to optimize its stiffness. This process often leads to creative configurations that produce complicated geometries challenging to construct using traditional techniques. Additive manufacturing has recently received a lot of interest from academics as well as industry. When compared to traditional methods, additive manufacturing or 3D printing offers considerable benefits (direct manufacture, time savings, fabrication of complex geometries, etc.). Recently, additive manufacturing techniques are increasingly being employed in industry to create complex components that cannot be produced using standard methods. The primary benefit of these techniques is the amount of creative flexibility they give designers. Additive manufacturing technology with higher resolution output capabilities has created a wealth of options for bridging the topology optimization and product application gap. This paper is a preliminary attempt to determine the key aspects of research on the integration of topology optimization and additive manufacturing, to outline topology optimization methods for these aspects with a review of various scientific and industry applications during the last years.
