| Abstract Scope |
The de-powdering stage in binder jetting additive manufacturing remains a manual and expensive post-processing step, creating a significant bottleneck that limits broader industrial adoption. This work presents an initial approach to automating the selection of both grasp location and applied gripping force for robotic handling, using material-specific surface friction data and the material’s maximum principal stress.
We model the statistical distributions of these properties and scale them using two reference points: the minimum normal force required to prevent slipping and the maximum principal stress observed when applying a 1 N load at candidate grasp points. With this normalization, we evaluate and rank potential grasps by minimizing the probability of either slippage or structural failure, enabling the selection of an optimal grip strategy. The method successfully predicts which part/grasp combinations lead to part failure during testing. |
