  Casting 3

Aluminium is, as before, a popular material to work with. We've complemented this paragraph with a video, which shows one of the most modern vehicles of the present time, the BMW i3. Although there is a lot of carbon to be seen, the flooring and the sills are made of aluminium, which doesn't have to be rolled but can be cast in the form that's needed.

You might indeed be amazed, at just how much aluminium is otherwise used. This time, for very complicated forms, which are perhaps manufactured very similar to that shown in the above film. Thereby, aluminium has a difficult stand, because special cast iron which can be cast in a very thin form, can almost completely compensate for this weight advantage.

Indeed, the production is also challenging. There's the problem of a lost die, or that the sand-form with the binding agent, can no longer be used as such, as is also shown in the film. On the other hand, sand without a binding agent can be reused without any special processing.

The challenge through the processing method shown right at the bottom, hasn't yet been completely decided. Will the 3D-printer only be used to produce the model for the above shown casting process or will it one day, be used to produce the required end-product itself, thus replacing the relatively complex casting process 02/15               Top of page               Index
