Granular gel as a 3D writing medium to create fragile and complex things like artificial jelly fish and can write and grow living tissue cells
University of Florida Researcher Angelini came up with the idea to use microscopic hydrogel particles as a medium for 3-D printing of soft matter. These particles are 99.8 percent water and 20 times smaller than the diameter of a human hair. He found that he could manufacture soft materials into shapes more fragile than anything …
