Abstract
Additive manufacturing has transformed traditional manufacturing paradigms by offering unparalleled design freedom and production efficiency. This thesis explores the optimization of additive manufacturing processes, focusing on topology, lattice parameters, and the fine-tuning of printing parameters in FDM technology.
The first aspect delves into topology optimization, a pivotal technique allowing for the creation of structurally optimized designs. By leveraging computational algorithms and simulation tools, this thesis investigates how topology optimization can be integrated into additive manufacturing workflows, enabling the creation of lighter, stronger, and more efficient parts. ANSYS Workbench alongside ANSYS Discovery, were used to simulate the various cases of topology optimization and lattice structures. A case study on a bracket was executed, where the bracket weight could be reduced to 23% of its mass. Many iterations were done to reach this solution. The research highlights the synergy between topology optimization algorithms and AM technologies to produce complex geometries that maximize structural performance while minimizing material usage. The shape obtained from the study could be manufactured with the aid of PBF technology. Meanwhile, casting was an option where the pattern could be made in a FDM machine.
Additionally, lattice structures play a crucial role in enhancing the mechanical properties of additively manufactured parts. This thesis scrutinizes various lattice parameters, including cell size, shape, and orientation, to optimize mechanical characteristics such as stiffness, weight, and resilience. Through empirical studies and computational simulations. It was found that the tetrahedral lattice structure may lead to higher design strengths than any other form. The diamond structure may produce flexibility in the body without losing strength.
Moreover, the research investigates the nuanced realm of printing parameters in FDM machines. It examines how adjustments in layer height, printing speed, temperature settings, infill patterns, and material choices impact the final part’s quality, structural integrity, and production time. The thesis emphasizes the significance of fine-tuning these parameters to achieve the desired balance between part quality, mechanical properties, and manufacturing efficiency. As one of the parameters studied was the impact of layer height on the tensile strength of the printed part and it was found that the smaller the height, the stronger the body
