https://www.rmit.edu.au/news/all-news/2024/feb/titanium-lattice

"inspired by hollow-stemmed plants combining strength, lightness... laser powder bed fusion metal 3D printing... hollow tubular titanium double lattice cube with thin band inside distributing stress evenly... 50% stronger than cast magnesium, halved stress concentrated on lattice’s weak points, deflecting any cracks... scale: several -mm to -m, bio-compatible, corrosion resistant, heat resistant as high as 350°C, goal: 600 °C using more heat-resistant titanium alloys for aerospace or firefighting drones... medical implants"
