This study aims to find a new lightweight and durable material for safety hook applications. The study requires experience in the necessary steps, starting from identifying the problem statement. The research objectives are to analyze the optimum infill settings for the PLA safety hook in achieving ultimate tensile strength via the Taguchi method. Finding out how to get the output and why to choose the strategy requires conducting a literature review. The ideal specifications for three-dimensional (3D) printers were a major focus of the literature review. Modeling the safety hook’s design using actual dimensions as a guide is crucial. The Taguchi method is used to generate numerous combinations of parameters and ranges. It was then converted to a stereolithography file and printed on a 3D printer. Each sample is placed directly into the universal testing machine for a tensile test. Computer-aided design software simulation was used to record and verify the results. The goal of the data analysis was to contrast the printed samples’ tensile strength characteristics with those of the pre-existing material used in the application. Correlating the best test results with the attributes of the already available material is essential. The data was subsequently confirmed, and the researchers concluded that PLA was suitable for use in safety hook applications utilizing an alternate fabrication method, i.e. 3D printing. After the validation process, formulating a determination is necessary as to whether all objectives were met or the opposite.
