Researchers have developed a new 3D printing technology that recycles wood waste material without using plastic. The 3D printed objects with the texture, appearance, thermal stability, and smell of natural wood
A great new use-case for wood waste.
Researchers from Rice University and Oak Ridge National Laboratory have developed a new 3D printing technology that recycles wood waste material. Also, in contrast with some other 'wood' 3D printing filaments available today, the new material is simply a water-based ink made of lignin and cellulose, the primary building blocks of natural wood – no plastics here. First, the freezing step: printed samples were put under dry ice for 30 minutes, then freeze-dried at -85 degrees Celsius at 0.1-mbar pressure, for 48 hours.
