Studies on design and analysis of gyroid structure using additive manufacturing process

This project confronts the limited research available on the Gyroid structure, majorly used to achieve weight reduction. The fascinating thing about the Gyroid is its geometry, capable of replacing the conventional solid models. This paper specifically investigates the tensile strength and the impact strength of the Gyroid structure and compare with the conventional solid structure. The design of CAD model for both solid and gyroid structures were done using Autodesk Fusion 360, a 3D modeling software. The novelty of the work lies on the design of experimental samples and the material used. The current work involves dog bone shaped specimens for testing purpose, but in most of the literatures testing involves numerical simulations, in some cases experimental testing were conducted based on the unit cell structure. The novel photopolymer UV curable resin with the curable wavelength of 405 nm was used as the raw material. By comparison, the solid structure is superior to gyroid structure in terms of ultimate strength and yield strength. But in contrary, the gyroid structure provides better outcomes compared to solid structure in case of elongation and impact strength.
