DensiCrafter: Physically-Constrained Generation and Fabrication of Self-Supporting Hollow Structures

The introduction of DensiCrafter marks a significant advancement in the realm of 3D generative models, which have revolutionized the synthesis of 3D geometry from various inputs. However, traditional methods often neglect the physical constraints necessary for practical applications. DensiCrafter overcomes this challenge by optimizing density fields to create lightweight, self-supporting hollow structures. This innovative framework integrates seamlessly with existing models like Trellis, enhancing their capabilities without requiring architectural changes. In extensive evaluations, DensiCrafter demonstrated a remarkable 43% reduction in material mass, which not only improves efficiency but also supports sustainability in manufacturing. The method's ability to maintain high geometric fidelity while improving stability compared to state-of-the-art baselines positions it as a pivotal tool for future 3D printing experiments, confirming its reliability and potential for real-world applicati…
