This paper addresses a structure design competition based on topology optimization and 3D Printing, and\nproposes an experimental approach to efficiently and quickly measure the mechanical performance of the structures\ndesigned using topology optimization. Since the topology optimized structure designs are prone to be geometrically\ncomplex, it is extremely inconvenient to fabricate these designs with traditional machining. In this study, we not only\nfabricated the topology optimized structure designs using one kind of 3D Printing technology known as stereolithography\n(SLA), but also tested the mechanical performance of the produced prototype parts. The finite element method\nis used to analyze the structure responses, and the consistent results of the numerical simulations and structure\nexperiments prove the validity of this new structure testing approach. This new approach will not only provide a rapid\naccess to topology optimized structure designs verifying, but also cut the turnaround time of structure design\nsignificantly.
