Abstract

This study aims to obtain optimal porosity results from bone scaffolding printing using FDM type 3D printing machines using PLA material. In this study, the bone scaffold was modeled using Solid Works. This research’s main contribution is to obtain optimal settings in the molding of bone scaffolding using the Taguchi method. The Taguchi method is used based on its efficiency; this is because orthogonal arrays require fewer experiments than experimental designs. Analysis of variance is needed to see the factors that have a significant effect on the response variable. The results showed that the factors that significantly affected the bone scaffold’s porosity quality were 42.22% nozzle temperature, 10.81% layer thickness, and 0.78% printing speed, respectively. The optimal operating parameter settings are at a nozzle temperature of 210°C, a printing speed of 25 mm/s, and a layer thickness of 0.1 mm, which are ideal settings for printing bone scaffolds so that porosity deviations can be minimized.
