Wood-filled filaments use a PLA base and combine that with wood particles. The exact type of wood used and its concentration varies between brands. Still, wood dust and cork are common, and most tend to be around 30% concentration. The presence of real wood particles gives prints a unique finish that looks and feels like real wood.
Unlike other composites, wood-filled filaments don’t need a wear-resistant nozzle. The wood particles are not harder than the brass used in most nozzles. Some wood-like filaments are purely colored to look like wood without actually containing any. It’s a good idea to double-check you’re actually getting what you want.

- Part Cooling Fan: Required
Best Practices and Tips
The added wood particles make wood-filled filaments likely to clog or partially clog the nozzle. Using a wider than normal 0.5mm nozzle can help resolve this. It’s recommended that you regularly manually clear any clogs from the nozzle.
The presence of the wood particles makes retraction settings unreliable as they interfere with the suction pressure after retraction. If offered, a “coasting” setting can help with this, as can setting the “extra restart distance” to a small negative number of -0.1 or -0.2mm. Enabling the “avoid crossing outline for travel movements” setting can also help by generally limiting any oozing to the structure’s internals where it isn’t visible.
- The wood texture finish looks good
- Doesn’t need wear-resistant nozzles
- Somewhat pleasant smelling
- Stringing is common
- Somewhat prone to clogging
- May require a larger nozzle
