The plastic shapes that RepRap prints can even be used as molds for casting metal objects, for example the Solar Turbine Prototype at Factor e Farm. Its primary feedstock is PLA (polylactic acid). This can be made by fermenting starch.
RepRap.org is the projects home page, and includes very clear instructions on how to build your own RepRap.
The open-source designs allow a great deal of flexibility and customization. A digitally-controlled tool that is free to move in three dimensions has many uses beyond 3D printing plastic. It has also been used to print circuit boards by replacing the plastic extruder head with a small router. The motors and control board have been adapted for our Torch Table
RepRap, like all healthy open-source projects, is continually evolving. The picture to the right shows the first generation, called Darwin. There is now a second generation RepRap called Mendel and there are prototypes of the third generation: Huxley. (All RepRap iterations are called after prominent biologists because RepRap is technology with the biological attributes of evolution and self-replication.)
- Also adaptable to solid state laser head, so it could do circuits via lithography?
- Connecting rods extrudable on a small scale, see Metal Extrusion Specifications
