An increasing number of additive manufacturing processes allows the user to design locally different material parameters. This may be achieved by using different process parameters or by combining different materials.
But what layout is optimal for a given range of material parameters. How can the service life be increased?
In the course of the Fraunhofer project "Cerimprint" the optimal layout for a component with different stiffness under indentation load was sought by finite element analysis.
By choosing an optimal layout the tensile stresses at the surface can be drawn into the component.
This can prevent the formation of cracks and the service life of the component can be vastly increased.
