Imitating wood’s ultrastructure with 3D printing for green products

The way by which wood develops is constrained by its genetic code, which gives it novel properties such as porosity, toughness, and torsional strength....
An Air Force Research Laboratory research team has developed a 3-D printed polymer-based foam structure that responds to the force of a shock wave to act as a one-way switch. These images show the material’s formation of jets, which localize shock wave energy in one direction, but not the other. (U.S Air Force photo illustration)
