Sinter-based Additive Manufacturing (SBAM) methods, such as Metal Binder Jetting, bridge the high productivity rate of series production and freedom of design in additive manufacturing. However, SBAM requires a subsequent sintering process to achieve the desired material properties, resulting in distortion due to anisotropic shrinkage and creep distortion. Simulative compensation of distortion is one solution to this problem.

In this work, the latest research results on the simulative prediction and compensation of distortion in SBAM from the Airbus Endowed Chair for Integrative Simulation and Engineering of Materials and Processes (ISEMP) at the University of Bremen will be presented. In particular, the newly developed method will be discussed in which the compensation of distortion is determined by the inverted simulation of the sintering process. This new numerical method allows to reduce the number of necessary iterations in comparison to conventional ones. The advantages of this method are demonstrated on the components with complex geometries having a high susceptibility for distortion.
