Because of some non-solvable problems with our second prototype, we wanted to improve our project by building a third machine, which would be able to work more precisely, is easier to transport, more modular and lighter in weight.
The choice for the frame soon fell on a very modular aluminium profile system, where we had the advantage to use numerous accessories to extend our 3D Printer.
By replacing the heavy steel tubes from our second prototype, and the help of many precise external parts, we were able to reduce the weight of an even larger machine, in comparison to its precursor, as well as its modularity and mobility. These aluminium profiles can be cut in every wanted length, and later be connected with some special internal connector plates, so we are able to scale up or down the printer in the needed size. Due to sliding carriages we were able to increase the building space.
