Abstract

The ability to manufacture customized parts has added a value to Additive Manufacturing (AM) process. The strength of additively manufactured parts largely depends on the process parameters associated with it. The current study is focused on parametric optimization of Fused Filament Fabrication (FFF) process by using Taguchi method for fabrication of lattice structures. Two different material TPU and PLA were chosen for conducting experiments and the impact of three process parameters: layer thickness, infill density and printing speed on the compressive strength of lattice structures was studied. S/N ratio and ANOVA analysis were performed to examine the importance of errors involved in experiments and finding the significance of each parameter. The layer thickness of 0.1 mm, infill density of 100% and printing speed of 40 mm/s was found to be the optimal combination for maximizing the compressive strength.
