Wood based 3D printing filament used in rapid prototyping with fused deposition molding (FDM) systems. This material is the first wood/polymer composite to be used in three-dimensional modeling. It has similar thermal durability as polylactic acid (PLA) and can be printed between 180°C (356°F) and 240°C (464°F). After printing it looks and smells like wood and can also be handled like wood. The warmer the processing temperature, the darker the filament will be; depending on the temperature, the printer can even print wooden-like objects with an annual tree ring-effect. Afterwards the printed objects can be cut, grinded or painted. It is composed of 40% recycled wood, has low shrinkage or warp while printing and is capable of printing bigger objects than standard acrylo-nitrile butadiene styrene (ABS) or (PLA). A 3D printing program first “slices” the object to be prototyped into many thin layers. Then a computer-aided design (CAD) file controls the laying down of thermoplastic material in thin layers corresponding to each thin slice (from the file), one on top of the other. As each layer is deposited, it bonds to the previous layer and solidifies, creating a three-dimensional object without using tooling. The polymer comes as a coil, 250 g (0.55 lb), 500 g (1.1 lb) or as a mono-filament: 1.75 or 3.0 mm (0.07 or 0.12 in) in diameter and can be printed into objects of any desired size. When printed at (180°C; 356°F) the color is from light brown to dark brown (240°C; 464°F). Applications include prototyping, architecture models and decoration.
