New 3-D-Printed Material Is Tough, Flexible—and Alive

They have created a 3-D-printed photosynthetic material using algae. Marie Aubin-Tam: We were interested in 3-D printing living material that’s made of microalgae. So they put it in agar on a petri dish, then place the bacterial paper above and print on that. Vitak: The bacterial paper stays on the print like a backing and provides the material with more strength than hydrogel prints alone. And some of their prints have been shipped to a few people’s homes—a kind of living material live test.
