> Instead of using steel to build certain high-strength components of an airplane, for instance, Carbon3D would be able to 3D print a lightweight alternative by shaping plastic into a form previously impossible to manufacture. This is what I'm most curious about. More specifically, I wonder if Carbon3D's device could be used for something similar to what Julia Greer is working on at Caltech (the nanotruss materials).
