Study on Characteristic Analysis of Onyx-Carbon Fiber Reinforced Material at Pt. Matahari Megah

Industry 4.0 focuses on automation with the help of technological and scientific developments in its application. Additive manufacturing is one of the pillars in Industry 4.0. 3D printing technology is part of additive manufacturing. One of the Indonesian companies that utilize 3D printing technology is PT Matahari Megah, the 3D-printing filament used to make a product in the company is Onyx-Carbon Fiber Reinforced. This material is used to make jaw grippers, soft jaws, threads, brackets, and jigs. However, the use of Onyx-Carbon Fiber Reinforced material is still not optimal, because there are no physical strength characteristics of the composite material. The method used in this research is to find a comparative study that starts by looking for literature studies that vary the parameters of the infill pattern and the percentage of density. In this study, the research data will be compared with the data from the literature study which will then be analyzed to find the most optimal parameters, based on the literature, the data obtained will be analyzed using the Taguchi method. From the data analysis, it is found that among the triangular, rectangular, and hexagonal infill patterns, the rectangular pattern is the most optimal. The optimal parameter configuration for the first data is by using rectangular infill pattern with 75% density percentage and for the second data by using rectangular infill pattern with 80% density percentage.
