Well I got bored and I went to the TPB website, I saw this RepRap thingy flashing in their website and I got this:

RepRap is short for Replicating Rapid-prototyper. It is the practical self-copying 3D printer shown on the right - a self-replicating machine. This 3D printer builds the parts up in layers of plastic. This technology already exists, but the cheapest commercial machine would cost you about €30,000. And it isn't even designed so that it can make itself. So what the RepRap team are doing is to develop and to give away the designs for a much cheaper machine with the novel capability of being able to self-copy (material costs are about €500). That way it's accessible to small communities in the developing world as well as individuals in the developed world. Following the principles of the Free Software Movement we are distributing the RepRap machine at no cost to everyone under the GNU General Public Licence.
So, if you have a RepRap machine, you can use it to make another and give that one to a friend...
Sure thing its a framework which looks interesting but boring. But hey, this thing right here is the future of Physical Object Sharing. For example, I have managed to prototype a special form of a rubiks cube with RepRap and I want it to send to you. Instead of sending the "Actual" object to you by parcel services, You have a RepRap machine, so I can just send to you the 3d file of the prototype I just made and its up to you to print the prototype in your RepRap machine.
Right now, the stable RepRap machine is the RepRap Version 1 "Darwin". It can rapid-prototype
almost everything. The version 2, which happens to be in beta right now and is open for everyone to use. The version 2 allows you to rapid-prototype objects with three-dimensional electrical circuitry inside mechanical parts!
Here's a link of some things this machine made:
ItemsMade < Main < Reprap
They have managed to make a flyswat, a pair of child's shoes, a water filter insert, a door handle and many more!
Advantages: It's nearly "FREE" to make one. If you have a friend who owns a RepRap machine then he/she can just make the parts of the RepRap machine for you!
Disadvantages: when I said "nearly free", that means you have to spend a little money. But seriously, who cares?
Right now I might just go into a hardware store and pick up some of the parts so I can start tinkering with it. Who's with me?
