The RepRap (a Rapid prototyping machine).

The RepRap. The reason for the need of an open hardware rapid prototyping machine is basicly the same as the reasons mentioned above for the CNC machine. Some parts can be made by CNC others cant - they have to be casted.. or made by eg. a RepRap. Why don't I write there is a need for a open hardware Rapid prototyping machine? because the RepRap IS open hardware - and its beautiful. I hope I get the possibility to get/make a RepRap in the near future, but judging from the website there is some way to go before this project is matured - but I like what I see.
