Conclusion The method to perform topology optimization with extension to variate material orientation has been performed. The analysis of applying distributed load on clamped bridge-like structure has been done. It was shown that two dimensional and three-dimensional cases have the same shape especially in regions near to outer surfaces of optimization volume. However, it is possible to see for three-dimensional case that secondary stiff elements, which support primary bars, have a slope in both planes of symmetry.
