Evaluation of Fused Deposition Modeling Process Parameters Influence on 3D Printed Components by High Precision Metrology

Additive manufacturing technologies are becoming an integral part of themanufacturing process in various fields ranging frommedicine and aeronautics to Industry 4.0 concepts due to their individualized generative design capabilities, high flexibility, compact production techniques, and direct CAD to product manufacturing capabilities. This increased utilization of additive manufacturing exposes the need for an in-depth analysis of the quality of parts obtained through these technologies and the factors that influence the dimensional and geometric precision and surface quality. This paper proposes a study on the effects of different parameters of the Fused Deposition Modeling additive manufacturing process on the quality and precision of the parts obtained through this process using PETG material. The parameters to be varied are temperature and speed. An analysis will also be performed to determine if deviations vary for the different lengths of the features. The results of the study indicate a correlation between process parameters and deviations, which can be used to create a mathematical model and apparatus to predict geometric and dimensional deviations and part behavior and to correct such errors during the design process, allowing for the manufacturing of precise parts and, in the future, the creation of a tolerance standard, leading to increased interchangeability between parts obtained through Additive Manufacturing techniques.
