Abstract

Layer-by-layer material deposition techniques are used in additive manufacturing (AM) procedures in order to produce complicated shapes. Designers may express themselves more freely via the use of these procedures, which are well-known for producing intricate structures that would be impossible to make otherwise. It is possible to modify technical processes and redesign items thanks to the advancement of additive manufacturing. Design optimization via the integration of topology optimization techniques is one of the most often used approaches to assist additive manufacturing, and it allows for the creation of complicated forms. Using Topology Optimization (TO), this research offers a comparison of design processes for Fused Deposition Modelling (FDM) 3D printing and gravity die casting with the objective of decreasing the mass of a Steel Clevis Bracket while fully satisfying the design limitation. You may mount a cylinder or even an ordinary rod on any flat surface with this bracket. It is specifically designed for 3D printing and uses a limited topology optimization method for component development. With the help of a simulation, the advantages of the proposed FDM 3D printing design framework are shown and confirmed. The simulation shows a 14% increase in factor of safety and a 39% decrease in the bracket's weight. The reduction in production time and cost are among the other benefits discovered. Traditional manufacturing has many design restrictions that FDM 3D printing overcomes.
