• Additive manufacturing continues to see increased growth and adoption across various industries owing to technology improvements and increasing material options. This paper presents a method to optimise the infill structure placement in fused deposition modelling parts. The method uses finite element analysis and the bi-directional evolutionary structural optimisation technique to determine the optimal placement based on stress and validated through testing 3D-printed samples. The results show that multi-infill geometry outperforms traditional rectilinear infill in loading capacity and stiffness. The paper concludes with a real-world application, using this optimisation method on a railway-related part.
