Collaborative project based learning in novel 3D printer design

This paper is a report on a comprehensive Problem-based learning (PBL) approach, applied in the frame of a final year project, in the study of Advanced Manufacturing and Mechatronics at RMIT University, and in collaboration with the industry. The main project objective, from the engineering point of view, was the development of a new product, 3D Printer for metal printing. From the engineering education point of view, we had problem definition, project organization and management, theory and practice integration, participants' directions, multidisciplinary team approach, collaboration and feedback at various levels and institutions. Additive manufacturing, or 3D printing, is emerging as a technology that is already changing engineering and manufacturing. Currently extensively used in prototyping, 3D printing practice is becoming more interesting with a wider choice of materials available. Company SPEE3D developed a process known as SPEE3D print, which enables metal components printing at higher speeds compared to conventional powder bed metal printers. RMIT University and SPEE3D have already established collaboration across a number of projects. Multidisciplinary projects are in the areas of robotics, mechatronics, industrial design, computational fluid dynamics and schlieren photography. The project presented here, was funded by Future Designers Grant from the Department of State Development, Business and Innovation, Victorian Government, Australia. Final product, new 3D printer, designed by students, has received a Bosch Venture Forum Award in Germany, in June 2015. This was a great international recognition of PBL student centred approach, applied in our engineering education practice, as well as University and industry collaboration, supported by Government funding.
