Dimensional Optimization of Additive Manufacturing Process

Abstract

Today, the use of layered production (3D printer) technology is becoming widespread. Prototype products can be manufactured by this method and also end-user parts as well. In this study, it is aimed to minimize the dimensional deviation of the parts obtained via 3D printing with PLA material. Within the scope of the study, 16 different experiments were conducted and five different parameters such as filling rate, printing speed, fill pattern, extruder temperature, and layer height were considered. For these parameters, four levels for each were determined and experiments were conducted. Then, Signal/Noise analysis was performed to determine the parameter levels that minimize dimensional deviations. Layer height and printing speed were identified to be important parameters in the final analysis
