This document discusses open source self-replicating 3D printers. It describes how 3D printers work by adding layers of material rather than subtracting material. It provides details on the history and development of RepRap 3D printers from 2005 to 2010. It also discusses the variety of materials that can be used in 3D printers and examples of real-life applications.
