Metal binder jetting - a new additive manufacturing process - allows the production of components with a high degree of complexity. However, differences in the process chain lead to special requirements for component design. The comparatively low strength of the green parts makes it difficult to reliably remove loose powder that sinters together with the component in the further course of the process chain and thus results in a partly irreparable geometric deviation. Corresponding design guidelines are currently only available to a limited extent. The aim of this article is therefore to identify process limits for the reliable design of boreholes and channels.
