At A Glance

Researchers at Colorado State University have developed a 3D-printed fabric that mimics the surface of shark skin. These surface features enhance certain textile applications and properties, including water drag reduction, mechanical properties, water wicking properties, and antimicrobial properties. The precision of 3D printing creates extremely biosimilar surface properties, which create the fabric performance. Ongoing study of the fabric has produced promising hydrodynamic, strength (durability), and antimicrobial data.

Background

Biomimicry has been recently recognized as an innovative strategy for developing functional clothing and textiles. In one biomimetic development, tooth-like structures, called denticles, covering the shark skin surface are believed to play an important role on hydrodynamic effects. Current similar products attempt to recreate the properties provided by the denticles by imparting some marginal texture to surfaces. However, these imitations may impart some properties but do not fully mimic the shark skin enough to provide all the properties thought to be provided by denticles.

Technology Overview

Researchers have utilized the precision of 3D printing to accurately recreate the shark skin denticle structure. By recreating the exact structure found on shark skin, researchers have discovered functional clothing may perform better than synthetic surface structures and impart the effects of natural shark skin. These structures provide hydrodynamic and antimicrobial properties, and have shown enhanced durability, and may lead to performance fabrics and clothing in many areas.
