Fused deposition modelling is an additive manufacturing technique, classified as one of the most popular 3D manufacturing processes, because of its low cost and easy usability, resulting in good quality products. However, the mechanical properties of manufactured pieces depend on the base material properties, manufacturing parameters, and room conditions (temperature and moisture). For those reasons, to obtain the optimal conditions, three different types of experimental tests were performed: tensile, flexural, and water absorption. These tests were carried out to determine ABS and PLA’s mechanical and physical properties, which are the main materials used in the FDM technique. Results showed that PLA has higher values of tensile and flexural strength comparatively to ABS and on the other hand, ABS had a greater weight of water absorption.
