Abstract:

Definition of the mechanical properties of the parts produced by the additive manufacturing method is of great importance for designers and users. In this study, the effects of the production parameters of the additive manufacturing method, such as nozzle, table temperature, and the variation of the filling pattern on flexural strength, are experimentally investigated. The test samples with different production parameters using ABS and PLA materials are produced with 3D printers. The produced samples are subjected to the three-point flexural test. As a result of the experiments, force-deflection curves are created. The effects of each parameter, and the results are evaluated. It has been determined that PLA is generally more durable in flexural strength than ABS. In addition, it is determined that the change of nozzle temperature for PLA material considerably changed its mechanical properties. The infill pattern change significantly changed the mechanical properties of both PLA and ABS material.
