Mechanical testing of polymer components made with the RepRap 3-D printer
| By Michigan Tech's Open Sustainability Technology Lab.
Wanted: Students to make a distributed future with solar-powered open-source 3-D printing.
|This page is part of an international project to use RepRap 3-D printing to make OSAT for sustainable development. Learn more.
Research: Open source 3-D printing of OSAT • RecycleBot • LCA of home recycling • Green Distributed Recycling • Ethical Filament • LCA of distributed manufacturing • RepRap LCA Energy and CO2 • Solar-powered RepRaps • solar powered recyclebot • Feasibility hub • Mechanical testing • RepRap printing protocol: MOST• Lessons learned • MOST RepRap Build • MOST Prusa Build • MOST HS RepRap build • RepRap Print Server
The purpose of this project is to determine mechanical properties of polymer components printed with the open source RepRap Mendel 3-D printer. Standard test methods are to be used to gather accurate and acceptable test data. The results of the mechanical testing will be used for engineering analysis of parts designed to be created with the RepRap.
The results are published here: B.M. Tymrak, M. Kreiger, J. M. Pearce, Mechanical properties of components fabricated with open-source 3-D printers under realistic environmental conditions, Materials & Design, 58, pp. 242-246 (2014). http://dx.doi.org/10.1016/j.matdes.2014.02.038. open access
