What is the Wood filament

Wood is already part of the materials that can be used in 3D printing. In addition, it has been one of our latest materials added on the web as a printing filament.

This material is formed by a PLA base with a mixture of wood chips (normally recycled) that accounts for between 20 and 25% of the final filament. Wood is used in molten filament printers, and is presented in the form of coils, just like PLA or ABS.

These wood shavings, apart from giving it texture and color, sometimes also leave a smell of wood, and it is an easy material to print, since the main material is the PLA.

Technology used

FDM or molten deposition modeling is a manufacturing process used for the prototype modeling and the production of small and medium runs . This modeling uses an additive function, depositing the material in layers, to form the piece.

A filament that is initially stored in rolls is used, and it is inserted into a nozzle that is above the melting temperature of the material and can travel in three electronically controlled axes. The nozzle moves to drop the material in the correct location, drawing the model line by line. When a layer is drawn, the base drops by a layer thickness (0.1-0.4) so that the printer can continue with the next layer.

When the model to be printed has sections that protrude or have a high angle, a support structure is created where it is considered necessary and printed on a material that can later be easily removed, in some cases soluble. This is done so that the model does not settle in the air, thus preventing the layer from falling.
