Material take-back programs for 3D printing are on the rise, as are technology advances geared toward recycling used prints and scrap into printable feedstock. Hosts Stephanie Hendrixson and Julia Hider discuss recent news and examples of recycling for 3D printing. Then, they look at examples of animals that have benefited from 3D printing and explore how these applications mirror and advance those in the human and industrial worlds.
