Using 3D Printers to Engage Students in Research

Is the primary purpose of a 3D printer to manufacture a product? Yes, but students and teachers can also use 3D printers to learn about and engage in research and experimentation. This could begin with product research and development, then expand to technical areas based on additive manufacturing technologies, the physical and mechanical properties of additive manufacturing materials, and the properties of 3D printed products. Student inquiry can take the form of formal or informal experimentation and observational studies. Although dedicated testing equipment can facilitate more demanding investigations, it is possible for quite a bit of experimentation to be done with little or no dedicated testing equipment. It is hoped that the reader will identify different educational experiences with experimentation that might fit their learners' needs and see 3D printers as tools for conducting and teaching about research, including product research and development and research into process engineering and materials.
