Abstract

Material Extrusion (MEX) involves the layer-by-layer deposition of a continuous filament to build a three-dimensional object in Additive Manufacturing (AM). This method stands out as a widely embraced and versatile AM process, renowned for its user-friendly nature, cost-effectiveness, and compatibility with a diverse array of materials. In this chapter, the mechanical properties such as tensile strength, compressive strength, and bending strength of composites fabricated with the MEX technique have been evaluated. Onyx polymer is used as matrix and fiberglass as reinforcement to create the composites. For the investigation, three types of specimens have been printed: first with only matrix material, second with only fiberglass, and third is the combination of both. In the first case, all 20 layers of the specimen are printed with only Onyx material with 100% infill density; in the second case, all 20 layers of the specimen are printed with only fiberglass material with 100% infill density; and however, in the third case, total 20 layers are printed with both Onyx and fiberglass with one layer of one material deposits over another one layer of other material until it reaches its 4 mm thickness. From the result of the tensile test, it can be concluded that Onyx + fiberglass has 30% more load-bearing capacity as compared to neat Onyx. Similarly, in the compressive test, it was found that neat Onyx was 76.4% stronger than fiberglass and 82.52% stronger than Onyx + fiberglass specimen. Lastly, the bending test showed that pure Onyx and fiberglass can withstand a maximum load of 0.4799 KN and 1.652 KN, whereas Onyx + fiberglass can withstand a maximum load of 1.156 KN. This chapter reports the findings of the mechanical characterization study conducted for the composite materials produced via the MEX process.
