An open source hardware-based mechatronics project: The replicating rapid 3-D printer

This contribution reviews the execution of an open source hardware (OSHW) project as part of the Master in Mechatronics Degree Programme at the University of Southern Denmark. There were a number of reasons that motivated us to carry out this project; educational, intellectual and research reasons. Open source projects provide unique opportunities for students to gain experience solving real-world problems. There was also a research consideration in pursuing an OSHW project. Three of the authors of this contribution are working towards a Master's Degree in Innovation and Business and wanted to carry out an OSHW project as a precursor to doing research work on the `Commercialization of OSHW Projects'. The choice of the project was all important and we choose to build a 3-D printer using information provided by the RepRap Open Source Community because this satisfied nearly all our specifications for an OSHW project. Our experiences in constructing a 3-D printer as well as documenting the areas where the open source information currently has deficiencies are documented here.
