'Mendel' - a second generation 3d RepRap printer with parts printed by first generation machines

Adrian Bowyer's personal 'Mendel' RepRap self-replicating 3D printer (Generation II), by Adrian Bowyer, Bath University,

Adrian Bowyer launched the RepRap project in 2005 with the goal of making 3D printing more accessible, and Ed Sells worked on it while studying for his doctorate at university. The software and designs needed are open source: free for anyone to download and use. RepRap’s own parts are printable, and just need to be assembled with off-the-shelf fixings. 3D printers enable people to create things they would otherwise buy, both saving money and reducing impact on the environment.
