Abstract

In this paper, we develop a smoothing algorithm that allows a subsequent production of components directly after topology optimisation. This is achieved by keeping features that are important for production, such as flat surfaces or straight edges. The algorithm works in two steps. The first step is based on the marching cubes algorithm and is necessary to prepare the optimisation result for the second step. The optimisation result consists of a density distribution and needs to be transformed to a surface representation without further material or density information. The second step makes use of an implicit method for smoothing surfaces, the so-called implicit fairing. The proposed two-step algorithm is exemplarily shown on two models. The results are compared to those received from a commercial solution to evaluate the quality of the algorithm. We show that the proposed algorithm allows a subsequent production directly after the optimisation and leads to results that are similarly good compared to those obtained by the commercial solution.
