Study on the Use of Polymer 3D-Printed Material for the Verification Process of a Metal Topology-Optimized Bracket

Original language description

The article proposes a cost-effective and rapid method for the preliminary verification of an optimized metal air brake bracket using a 3D-printed polymer model. The original bracket, used in light jet aircraft, is made of the aluminium alloy Al 2024 T351 and manufactured using conventional CNC machining technology. The study presents a structural optimized bracket, intended to be produced using 3D printing technology with AlSi10Mg material to reduce weight. The bracket is presented along with its static load, stress-strain analysis, and the weight structural optimization procedure using ANSYS Workbench. Modifications to the bracket's shape were made to meet the static stress-strain and buckling characteristics of the original bracket, resulting in a 32% weight reduction. The complex model of the optimized bracket was verified both numerically using ANSYS Workbench and experimentally using 3D-printed bracket models made from substitute polymer ASA material, printed with the Prusa Mk3 printer. The article also presents the results of basic tensile material tests on ASA material coupons printed in various positions to determine the semi-isotropic characteristics necessary for numerical analysis. The substitute material bracket provides potential for indicative verification of the numerically optimized model, though its usage is limited. Finally, the article offers recommendations for further research.
