3D Printing with Wood

Jun-18-15 A new 3D printer able to print objects from wood pulp could offer an eco-friendly alternative to the more toxic plastic-based versions.

Developed by a team from Chalmers University of Technology, the printer creates its objects using nanocellouse that was derived from wood pulp—the material responsible for the trees’ sturdy trunks. Since cellulose won’t melt—a requirement for 3D printing—the team mixed it with a hydrogel (and occasionally carbon nanotubes) so the material would flow through the printer. The resulting structure was then dried in a controlled environment so it would retain its shape.
