Researching the Effect of Parameters Process on the Tensile Strength of FDM Products Using ABS Material

FDM (Fused Deposition Modeling) has currently been expanding quickly and controlling a substantial market share in additive manufacturing. In critical sectors including the automotive, maritime, and manufacturing industries, this technology is employed not only for prototyping but also for the production of finished goods. This pattern suggests that the mechanical characteristics of FDM products, in particular, require higher standards. The aim of this study is to investigate and assess the impact of five crucial technological parameters on the tensile strength of test specimens produced on an open-source 3D printer with a system of providing and controlling temperature for the product fabrication chamber using ABS material in accordance with ASTM D638-14 standard. Each experimental parameter is layer thickness, velocity extruder, angle raster, infill density, and chamber temperature. The second-order experimental planning approach RSM (Response Surface Method), with three levels of values for each parameter, was used for the experimental design and analysis. The findings show that the mechanical properties of the product are significantly enhanced with the optimized parameters when a temperature value is kept around the product fabrication zone to prevent overstress between layers. The highest tensile strength of the specimen is 49.5178 MPa.
