Study of mechanical and antimicrobial properties of biomimetic shark skin fabrics with different denticle size via 3D printing technology
Altmetrics
Abstract
Previous studies have shown that biomimetic shark skin fabrics can reduce water drag and increase swimming speed. It was also known that the smaller the denticle was, the higher water drag reduction was. In nature, the size of the denticles on shark skin is between 100 μm and 500 μm. However, the minimum size of the 3D printed denticles on a biomimetic shark skin fabric previously reported was about 2mm, which was still much larger than the natural size. In this study, different sizes of denticles ranging from 0.65mm to 1.30mm were fabricated using a Form3 3D printer and Flexible80A resin, and ...
