Julia Greer answers questions about additive manufacturing

    Professor Julia R Greer is a materials scientist at the California Institute of Technology. Her group focuses on designing, fabricating and characterising micro- and nano-architected materials using 3D lithography, nanofabrication, and additive manufacturing (AM) techniques for a multitude of applications ranging from biological devices to damage-tolerant fabrics.

    There has always been a duality between material and structure, and additive manufacturing enables us to couple these properties. We can envision a day where we have a backpack with supplies and we can use natural resources and the natural habitat to set up a little 3D-printer and create power and energy sources and whatever else we may need: solid state batteries, fuel cells… Additive manufacturing allows us to dream big, which is what I like doing. While I’m not sure of the timeframe, it really paves the way for a future world where everything is going to be done by design according to utility.
