RepRap
RepRap is an open-source project that aims to create a self-replicating 3D printer. It allows users to produce most of its components using the printer itself, making it a cost-effective and accessible option for hobbyists and engineers. The project encourages innovation and collaboration within the 3D printing community.
The first RepRap model was developed in 2008 by Adrian Bowyer, a lecturer at the University of Bath. Since then, various versions have emerged, each improving on the design and functionality. The project has significantly contributed to the growth of the 3D printing industry and has inspired many similar initiatives.
