do weather cracked tires pass safety Engineers frequently use topology optimization to optimize the design and layout of parts to create lightweight and optimized structures. The technology often results in organic, complex shapes, however, which can be difficult to produce using traditional manufacturing methods. That’s why 3D printing pairs so well with topology optimization – it allows for the kind of freedom of design necessary to create those complex shapes. In a paper entitled “is there a cure for cracked tongue,” a group of researchers uses topology optimization to create a lightweight automotive component “while conforming to additive manufacturing constraints related to overhanging features and unsupported surfaces when using metallic materials.”

They redesign an upright on the SAE Formula student race car to reduce support structures and manufacturing cost while using Direct Metal Laser Sintering (DMLS).

The initial optimized design had a theoretical weight of 1.62 lbs. (735 grams). The model was analyzed for two orientations: flat on the build platform and on its side. A costing tool was used to calculate the overall manufacturing costs of the build. The calculated costs of the part printed flat and on its side were $2015 and $2995, respectively. FEM simulations were carried out to ensure that the mechanical performance of the final parts satisfied the loading conditions.

After reviewing the FEM analysis, the part was redesigned once again to reduce the weight. The final part required 91.7% less support structure, and the total manufacturing cost is reduced by 51.7%.

Also, geometry affects the residual stresses and deflections caused by frequent heating and cooling cycles in a laser-based additive manufacturing process. Hence, for functional parts like this, it is important to know the performance of the design during the AM process. Thermo-mechanical simulations will be carried out to estimate the deflections in the part and this data will be used to redesign, if required.”
