3D Printing Multiple Colors with a Single Extruder Printer

In this video I show how you can print objects using multiple colors with a single extruder printer, as for example the Velleman K8200. You can switch colors in between layers, which can create nice effects (depending on the actual object you want to print). I create the 3D model of the text plate with Autodesk 123D Design, which is really nice and free software. Please leave comments if you are interested in a tutorial on how to create such a plate with 123D Design - I could create a short video about this topic.
