Basic info
Composite materials filled with metal or wood powder are usually PLA filaments. The additives give them a special look and properties. They are hard to print due to a higher risk of clogging the nozzle. Metal-filled filaments also require a hardened nozzle.
 
Recommended nozzle temperature: 190-220 °C (depending on filament type)
 
Recommended bed temperature: 60 °C
 
Heatbed: Smooth PEI sheet will provide the best adhesion.

Wood or metal powder-filled filaments serve mostly for aesthetic purposes, imitating the chosen material (wood or metal). However, note that they have much worse mechanical resistance and layer adhesion than non-modified filaments. The basic material is usually PLA, which is known for easy printability, but inferior chemical, mechanical, and heat resistance.

Metal-filled materials are highly abrasive and require a hardened steel nozzle. For wood-filled materials and other composites with large particles, we also recommend using, minimum, a 0.6 mm nozzle, and 0.2 mm layer height to prevent clogging.

Due to the brittleness of these filaments, we do not recommend printing them with the MMU2S upgrade.

To compare supported material properties, see PLA. Metal filaments can be polished to reach an authentic metal look (but not mechanical properties). Polish metal-filled materials in a similar way you would do it with transparent parts: gently sand the surface with wet sanding papers with 600-1500 (or higher) grit, start with the roughest, and end with the finest. Then use polishing paste and a piece of cloth. Remember that powder-filled filaments have inferior mechanical properties and layer adhesion. If your print has some protrusions and surface details, they can break easily.

I am trying to print with ERYONE Wood PLA, and it is not sticking to the bed I tried creating a filament preset wit the paramaters on the spool and product documentation but it just doesn't stick. Any help or suggestions appreciated

Hello, thank you for your comment, and sorry for the issue. If this is still an issue, it is likely not an issue with the particular spool, but more on the cleaning techniques for the sheet. 
I'd recommend checking the aspects in this paragraph of the smooth sheet guide and in more detail the aspects in the following guide for first-layer issues. The issue at hand is most likely related to the sheet preparation.
