AB  - Tensile testing is a popular laboratory experiment for several engineering disciplines. A new technique in teaching this lab is to use additive manufactured plastic specimens. As more and more plastic is used in the industry students need to be aware of the specifications of these materials. Following ASTM 638 standards, 3D printed plastic materials were studied for their potential applications in engineering education. Using the tensile test, the stress strain curves of the materials have been measured. The Young's modulus, ultimate strength, and fracture toughness of the materials are calculated from the stress strain curve. Results show that carbon fiber reinforced polymer (CFRP) has the highest stiffness or Youngs modulus. Acrylonitrile butadiene styrene plus (ABSplus) has strongest mechanical properties, with highest ultimate strength and fracture toughness. With the measured properties, the 3D printed samples may be a viable solution for engineering students to learn mechanical properties of materials. This work will look at the impact of the curriculum. Future work includes using multiple tensile testing machines and determining if the use of metal specimens are needed for student learning outcomes. We will provide a summary of the student outcomes. We analyzed student work using analysis methods.
