Scale – Nano. Wood offers us several scales to work with, from tiny nano crystals thru to the placement of full logs.
Let’s start small, a team in Chalmers Sweden are printing wood at a nano scale. http://www.chalmers.se/en/departments/chem/news/Pages/Cellulose-from-wood-can-be-printed-in-3D.aspx. At this scale, the amazing thing about NanoCrystaline Cellulose (NCC) is that the material can self assemble, no need for heat, binders or adhesive. It could literally be grown as a crystal that is amazingly strong, lightweight and conductive. Several industries are excited about possibilities including defence, automotive/aerospace, medicine or high tech. It seems that additive manufacturing is the only approach to take when placing NCC, so is a 3D printer the right tool? http://www.extremetech.com/extreme/134910-nanocellulose-a-cheap-conductive-stronger-than-kevlar-wonder-material-made-from-wood-pulp.
NCC can also be added as a reinforcement to other filament material, like plastic, or paste material, like concrete. However filaments bring us to the next scale, the table top.
