The newest RepRap, RepRap Version II "Mendel", will be released very shortly.  It is both bigger and smaller than RepRap Version I "Darwin": it can make bigger things, but the machine itself is physically much smaller.  It is genuinely a desktop portable 3D printer - you can carry it in one hand.  It's also a lot easier to put together than RepRap Version I "Darwin".  All of Mendel's printed parts can be printed in Darwin, and, of course, in itself.

Look at your computer setup and imagine that you hooked up a 3D
printer. Instead of printing on bits of paper this 3D printer makes
real, robust, mechanical parts. To give you an idea of how robust,
think Lego bricks and you're in the right area. You
could make [[http://www.thingiverse.com/tag:reprap][lots of useful stuff]], but interestingly you could also make
most of the parts to make another 3D printer. That would be a machine
that could copy itself.

<font style="color: rgb(0, 150, 0);">RepRap</font> is short for <font style="color: rgb(0, 150, 0);">Rep</font>licating <font style="color: rgb(0, 150, 0);">Rap</font>id-prototyper.  It is the practical self-copying 3D printer introduced in the video 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 &euro;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 &euro;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 [[http://www.fsf.org/][Free Software Movement]] we are distributing the RepRap
machine at no cost to everyone under the [[RepRapGPLLicence][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...

The RepRap project became widely known after a large press coverage in March 2005, though the idea goes back to a [[BackgroundPage][paper on the web]] written by [[http://en.wikipedia.org/wiki/Adrian_Bowyer][Adrian Bowyer]] on 2 February 2004. 

RepRap Version I "Darwin" can be built by anyone now - see the [[RepRapOneDarwin][Make your own RepRap]] link there or on the left, and for ways to get the bits and pieces you need, see the [[PartsSupplies][Obtaining Parts]] link. RepRap Version II "Mendel" will be released in a matter of days.

Adrian Bowyer (left) and Vik Olliver (right) with a parent RepRap machine, made on a conventional rapid prototyper, and the first 
complete working child RepRap machine, made by the RepRap on the left.  The child machine made its first successful grandchild part at 14:00 hours UTC
on 29 May 2008 at Bath University in the UK, a few minutes after it was assembled.

Not counting nuts and bolts RepRap can make 60% of its parts; the other parts are designed to be cheaply available everywhere.  This is an interesting coincidence: we can make 60% of our proteins; the other parts are evolved to be cheaply available everywhere...

The primary goal of the RepRap project is to create and to give away a makes-useful-stuff machine that, among other things, allows its owner cheaply and easily to make another such machine for someone else.

To increase that 60%, the next version of RepRap will be able to make its own electric circuitry - a technology we have already [[http://staff.bath.ac.uk/ensab/replicator/Downloads/report-01-04.doc][proved experimentally]] - though not its electronic chips.  After that we'll look to doing transistors with it, and so on...
