Wood 3D printing was born around 2012. The first filaments were PLA-based filaments with integrated sawdust. The early experiments, however, showed that sawdust wasn’t the best solution for either wood 3D printing nor wood filaments.
These days, wood filament is still PLA-based, but the wood is instead integrated in the form of wooden fibers. Many different types of wood have emerged, as well! You can now choose between birch, coconut, bamboo, timber, cedar, and many others. Typically, wood filaments contain 70% PLA and 30% wooden fibers, but it all really depends on the filament manufacturer.
Despite this seemingly low fraction of wood, we guarantee you’ll be impressed with just how wood-like the resulting prints feel. From texture to smell, everything feels very real. This means wood 3D printed parts can be treated as real wood. In other words, it’s safe to sand the parts and apply different paints and coatings.
One thing to keep in mind that you might not be aware of is the smell of melting wood filaments. During printing, it basically smells like burning wood. So be sure to have proper ventilation and to stay out of the room during the whole print. You don’t want to breathe in the fumes!
In the following paragraphs, we present some of the best and most popular wood 3D printing filaments.
