Bio-inspired 3D-printed lattice structures for energy absorption applications: A review
Ramakrishna Doodi, Gunji Bala Murali
Abstract
The biomimetic approach rapidly evolves for designing novel lightweight structures and has been expanding in engineering design. Additive manufacturing or 3D printing permits three-dimensional parts to be fabricated with an intricacy and quality that might be tough or impossible to appreciate with the present traditional production techniques. With the probabilities and exactitude, 3D printing allows bio-inspired lattice structures from nature that are hypothetically advanced to ingest excellent energy absorption capacity with less material. The combination of additive manufacturing with cellular lattice architectures offers potential design options regarding material utilization, strength, cost, and component weight. A summary of recent advances in the improvement of bio-inspired structures is outlined in this review paper. Specifically, exciting highlights and remarkable mechanical properties of bio-inspired structures of bones, teeth, and dermal layers of creatures might be bio-mimicked to style economical energy absorbers. Researchers and engineers can use this information to create unique designs inspired biologically for the application of absorption energy.
