In the heart of Turkey, researchers are turning to nature for inspiration, pushing the boundaries of what’s possible in the world of additive manufacturing. Turker Turkoglu, a mechanical engineering professor at Balıkesir University, has been leading a team that’s exploring the potential of bio-inspired lattice structures, and their findings could revolutionize the way we think about lightweight, high-strength materials in industries like energy.
The team’s latest work, published in Materials Research Express, delves into the world of metallic hybrid lattice structures, drawing inspiration from the intricate, hierarchical architecture of coral formations. Using the Laser Powder Bed Fusion (L-PBF) technique, they created three unique hybrid lattice configurations from AlSi10Mg: GiG (Gyroid inside Gyroid), GiD (Gyroid inside Diamond), and GiS (Gyroid inside Schwarz). Each configuration was designed to explore how internal topology influences mechanical behavior.
The results are impressive. The GiS configuration, with its combined stretch- and bending-dominated characteristics, demonstrated the highest compressive strength (134.35 MPa) and energy absorption capacity (80.14 MJ m ^−3). “This isn’t just about creating lighter structures,” Turkoglu explains. “It’s about creating structures that can withstand more, absorb more energy, and ultimately, last longer.”
So, what does this mean for the energy sector? In an industry where weight and strength are constant considerations, these bio-inspired lattice structures could be a game-changer. Imagine wind turbine blades that are lighter, stronger, and more resistant to fatigue. Or offshore platforms that can withstand the harshest conditions without compromising on weight. The potential applications are vast, and the implications for the energy sector are significant.
But this is just the beginning. Turkoglu and his team are already looking ahead, exploring how these bio-inspired designs can be adapted for other materials and applications. “We’re not just mimicking nature,” he says. “We’re learning from it, and using that knowledge to push the boundaries of what’s possible in additive manufacturing.”
As we look to the future, it’s clear that bio-inspired design is more than just a trend—it’s a paradigm shift. And with researchers like Turkoglu at the helm, we can expect to see some truly groundbreaking developments in the years to come. The research, published in Materials Research Express, is a testament to the power of interdisciplinary thinking and the potential of bio-inspired design to shape the future of manufacturing.
