Life Lessons: Architects turn to biology for solutions to all that ails us.

Biological materials and the processes through which they're generated represent the fruits of about 3.8 billion years of research and development. And unlike, say, concrete manufacturing (which is responsible for 4 to 8 percent of the world's CO2 emissions), this natural carbon-sequestering process is environmentally benign. Discuss the role of additive manufacturing techniques in the fabrication of biomimetic materials. [Extracted from the article]
