Topology optimization is a computer-based calculation method that can be used to determine a favourable basic shape (topology) for components under mechanical load. It is typically used in aerospace technology, automotive and vehicle construction and also others branches of mechanical engineering.

The starting point for this method is a geometric body, which represents the maximum amount of space that is available for the component being developed. This body is described as the "design space". The results of the calculation provide information on the optimum layout of materials within sections of the design space.


The use of topology optimisation makes it possible to mechanically optimise components and reduce the amount of materials used. Cost savings and the possibility of reducing weight demonstrate the enormous economic potential of this technology.

In particular, new possibilities for geometry optimization are being opened up in combination with laser melting processes for metals. It thus becomes possible to develop hollow bionic structures that display the highest material strengths at the lowest weights.
