According to the abstract released by the Intellectual Property India: "Lattice structures obtained by additive manufacturing have high strength-to-weight ratios but they tend to lose their capacity to respond to different stress distributions during actual mechanical loading. Fixed geometry lattices experience localised stress localisation which results in material fatigue, decreased durability and sudden failure under extreme conditions. The proposed system has an additive-manufactured lattice with stress-adaptive morphology, which aims to adaptively change their geometry according to the applied load conditions. The lattice uses the micro-deformation zones and variable-density areas that allow adjusting the shape as desired without the reduction of the structural integrity. These adaptive regions are positioned strategically using topology optimization and are produced using selective laser sintering, fused deposition modeling or electron beam melting techniques. In response to external stress which exceeds a certain calculated value, the internal lattice geometry is controlled to deform and reallocate the load in adjacent areas, thereby avoiding stressed points. A built-in pathway of morphological adaptation ensures that once the stress levels are decreased, the structure can heal itself, allowing partial self-recovery of geometry. This approach improves fatigue resistance, impact absorption and longevity of lightweight structure used in aerospace components, automotive frames, biomedical implants, protective gear or structural reinforcement materials used for heavy structures. The system supports the multi-material manufacturing situation and can customize the density of the lattice according to the application-specific requirements. In terms of its adaptive behaviour, its load distribution performance is superior than conventional static lattice structures. Through stress-guided deformation process and topology-controlled adaptation, the proposed lattice framework is a significant progress in the field of smart structural materials, which can keep the materials reliable under fluctuating mechanical conditions."
