Reprap Prusa Iteration 2 Build Event in Cologne Germany in December

German description at

A reprap build workshop is going to take place in Cologne, Germany on the first weekend of December (3-4.12). Ten groups will have the opportunity to build their very own 3d printer, get it working, and take it home with them.

Under the guidance of Josef Prusa, Kliment Yanev and Ruben Lubbes, we’ll build ten printers of the latest Prusa Iteration 2 variety. More info on Prusa iteration 2 at Prusa Iteration 2

After building the printers, we’ll look at control and design software, basic troubleshooting, and where to get designs, ideas, and help. At the end of the workshop, every participant or group will go home with a working printer.

Here is a video of an earlier workshop organized by the same team:

Workshop data:
Time: 3rd and 4th of December 2011, from 10.00h to 19.00h on both days. Impatient builders may continue past 19h on Saturday if they wish to, but that should not be necessary.
