In this study, numerical simulation for topology optimization and 3D printing for stiffness maximum structure are carried out. The stiffness maximum structure expressed by optimal density distribution is iteratively computed by using the gradient of the Lagrange function with respect to the density. In this computation, the filtering technique for the gradient is introduced, and the update of the density value is carried out based on optimality criteria method. In numerical experiments, considerations for the stiffness maximum structure is also performed.
