Researchers have developed a high-resolution embedded 3D-printing technique that enables the fabrication of ultra-fine fibers, mimicking nature’s structures. Using a solvent exchange process, they achieved unprecedented resolutions of 1.5 microns, unlocking new possibilities for bioinspired materials and advanced engineering applications.

Researchers have been exploring new methods to produce and replicate the diverse and valuable features found in nature. Fine hairs and fibers, which are ubiquitous in the natural world, serve various purposes, from sensory functions to contributing to the unique consistency of hagfish slime.

MechSE Professors Sameh Tawfick and Randy Ewoldt, along with doctoral candidate M. Tanver Hossain and external collaborators, have addressed this need using their advanced embedded 3D-printing technique, recently published in Nature Communications.
