'Darwin' RepRap self-replicating 3D printer (Generation I), by Adrian Bowyer, Bath University, 2007

This is Adrian Bowyer’s first RepRap self-replicating 3D printer. Adrian launched the RepRap project in 2005 with the goal of making 3D printing more accessible. 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.
