Abstract: Manufacturing (AM) enables the production of lattice structure architecture due to its capability to produce complex geometries. Lattice structure is a design that contains a space-filling unit cell that can be tessellated among any axis. It is an analytic design to reduce mass and weight of the object. However, many challenges arise in the AM- printed lattice such as warping, shrinkage, elephant foot, first layer problem, surface finishing and mechanical properties especially when fabricated using fused deposition modeling (FDM) technique. Hence, this study aims to optimize the influence of process parameters of collinear lattice FDM printed part using Taguchi. Meanwhile, S/N ratio was used to find the optimal process parameters in improving the printing quality. Other than that, the analysis of variance (ANOVA) was used to provide the significance ranking of various factors analyzed. From the results, it was found that the layer thickness is the most significant factors that affect the maximum force (N) of collinear lattice structures. In addition, this study was conducted to assist the fabrication of printed part for the structural applications.
