The machine on the right is the RepRap printer, which we call "Mendel" after the father of genetics. It's the second, improved version of RepRap: small enough to fit on your desk, but with a print volume large enough for you to make big things (see specifications below). The machine is made up of bits bought in from local suppliers or online, and parts which it can make for itself - all the translucent structural components you can see. In the picture, behind the machine, you can see the RepRap software which you can use to print your thing. We give this, and the designs for the machine away, free - it's all open source (GPL 2). Though you do have to buy in some standard components from... well, whoever you want... which cost about €400. The idea of getting all the materials and building a machine yourself may seem daunting, but this area of the wiki is dedicated to making the whole process as easy as possible. Click a "How To ...." link above for building and using tips and more.... There are a number of instructional videos distributed through the Mendel documentation. These are also all gathered together in one place here. You can see examples of people's Mendels, and where they got their parts at Mendel Source Logs.
