Resumo(s)
This study investigates the use of topologically optimized filling in additive manufacturing to
enhance the strength-to-mass ratio of 3D printed parts. The research utilized SolidWorks
modeling, adhering to the ASTM 695-15 standard, with optimization focused on various
symmetries and preserved regions to maximize structural efficiency. The specimens were printed
using Anycubic Kobra 2 Neo 3D printers and ABS filament, and the optimized models were
compared to those with standard fillings (grid and triangular) through compression testing. The
results showed that while the optimized filling achieved only 50% of the strength of the standard-
filled models, the grid pattern outperformed the others, demonstrating superior performance and
ductility. Ultimately, the study concluded that the optimization process did not surpass the
performance of the standard meshes generated by 3D printing slicers.
