Neuro-symbolic control architecture enhances laser powder bed fusion quality

Researchers have developed a novel neuro-symbolic closed-loop control architecture for laser powder bed fusion (LPBF) additive manufacturing. This system integrates symbolic reasoning with statistical learning, using an in-loop ontology to translate process objectives and constraints into actionable targets for a predictive controller. The architecture effectively manages quality limitations like overhang dross by mapping unmeasurable process parameters to observable ones, demonstrating feasibility and potential for adaptation to new materials and constraints.
