Abstract

The utilization of carbon fiber 3D printed specimens is progressively expanding across various applications that need exceptional levels of strength and stiffness. Nevertheless, the impact strength of these specimens may be influenced by several parameters, including carbon fiber content, infill pattern, density, printing speed, and layer thickness. This research study uses the design of experiments (DOE) methodology to examine the parameters that influence the impact strength of carbon fiber 3D printed specimens. A statistical model has been established to forecast the impact strength of carbon fiber 3D printed specimens, taking into consideration the elements. The study's findings indicate that the impact strength of carbon fiber 3D printed specimens is mostly influenced by the infill density in comparison to other parameters. The impact strength is significantly influenced by the interaction effects of layer thickness, infill pattern, and infill density. The statistical model created in this research may be used to ascertain the most suitable amalgamation of variables to get the intended level of impact strength for a certain application. This phenomenon has the potential to enhance the overall performance, longevity, and safety attributes of many items.
