Additive manufacturing methods are being taught widely in many universities and schools. Students learn how to use 3D printers to make their designed parts, but they usually do not measure the mechanical and surface properties of their additively manufactured parts to compare the new materials with the conventional materials such as steels, aluminums, and injected polymers. This article summarizes some of the standard applicable testing methods for testing the mechanical and surface properties of additively manufactured test samples in universities. In the presented model, students use polymer or metal 3D printers to manufacture their test samples for tensile, impact and hardness test equipment to measure the mechanical properties of the printed materials. They also measure and compare the surface properties such as surface roughness, metallography and microstructure, and resistance against wear, abrasion, and corrosion. The presented model is intended to provide students with a general idea about the usefulness of AM materials and the probable differences between them and conventional materials. The model can be developed as a new course or be added to the additive manufacturing or material science courses in sophomore or junior levels.
