The short answer is: it depends. Wood filament can damage your nozzle if it is not properly cleaned, maintained, or used with the right settings. However, with some precautions and best practices, you can print with wood filament without damaging your nozzle.
Wood filament is a type of composite filament that contains wood particles mixed with a thermoplastic base, such as PLA or ABS. Wood filament can create prints that have a natural wood-like appearance, texture, and smell. Wood filament is also biodegradable and eco-friendly, making it a popular choice for many 3D printing enthusiasts.
However, wood filament also has some drawbacks and challenges that you need to be aware of before using it. One of the main concerns is the potential damage that wood filament can cause to your nozzle. In this article, we will explain why wood filament can damage your nozzle, how to prevent or minimize the damage, and what to do if your nozzle gets clogged or worn out by wood filament.
Wood filament can damage your nozzle for several reasons:
Wood filament is abrasive. The wood particles in the filament can act like sandpaper and wear down the inner surface of your nozzle over time. This can reduce the nozzle’s diameter, affect the extrusion quality, and cause under-extrusion or over-extrusion problems.
Wood filament is prone to clogging. The wood particles in the filament can also accumulate inside the nozzle and create blockages. This can happen if the filament is not dry enough, if the nozzle temperature is too low, or if the retraction settings are too high. Clogging can prevent the filament from flowing smoothly and cause extrusion issues or nozzle jams.
Wood filament is sensitive to heat. The wood particles in the filament can burn or char if the nozzle temperature is too high or if the filament stays in the nozzle for too long. This can create carbon deposits inside the nozzle that can harden and obstruct the nozzle opening. This can also affect the color and quality of your prints.
How to Prevent or Minimize Nozzle Damage from Wood Filament
To prevent or minimize nozzle damage from wood filament, you need to follow some precautions and best practices:
Use a larger nozzle size. A larger nozzle size can reduce the abrasion and clogging caused by wood filament. A larger nozzle size can also allow for faster printing and better layer adhesion. The recommended nozzle size for wood filament is 0.4 mm or larger.
Use a hardened steel nozzle. A hardened steel nozzle can resist the abrasion and wear caused by wood filament better than a brass nozzle. A hardened steel nozzle can also withstand higher temperatures and last longer. However, a hardened steel nozzle may require higher temperatures and slower printing speeds than a brass nozzle.
Use the right temperature settings. The optimal temperature settings for wood filament depend on the type and brand of the filament, as well as the nozzle size and material. Generally, wood filament requires lower temperatures than pure PLA or ABS, as higher temperatures can cause the wood particles to burn or char. The recommended temperature range for wood filament is between 175°C and 230°C, depending on the filament and nozzle specifications.
Use the right retraction settings. The retraction settings control how much the filament is pulled back into the extruder to prevent oozing or stringing. However, too much retraction can cause the wood filament to clog or jam the nozzle, as the wood particles can get stuck inside the nozzle. The recommended retraction settings for wood filament are between 1 mm and 3 mm, depending on the filament and nozzle specifications.
Keep the filament dry. Wood filament can absorb moisture from the air and become brittle or swollen. This can affect the print quality and cause the filament to break or clog the nozzle. To keep the filament dry, you should store it in a sealed bag with desiccant packets, or use a filament dryer or dehumidifier during printing.
Clean the nozzle regularly. To prevent the nozzle from getting clogged or blocked by wood filament, you should clean the nozzle regularly. You can use a needle or a wire to poke through the nozzle opening and remove any debris or residue. You can also use a cold pull or an atomic pull technique to clean the nozzle. This involves heating the nozzle to a high temperature, inserting a cleaning filament or a pure PLA filament, cooling the nozzle to a lower temperature, and then pulling the filament out with a quick motion. This can help remove any impurities or contaminants from the nozzle.
What to Do If Your Nozzle Gets Damaged by Wood Filament
If your nozzle gets damaged by wood filament, you may need to replace it with a new one. You can tell if your nozzle is damaged by wood filament if you notice any of the following signs:
The nozzle’s diameter is visibly reduced or enlarged.
The nozzle’s opening is visibly deformed or misaligned.
The nozzle’s surface is visibly scratched or corroded.
The nozzle’s extrusion is inconsistent or irregular.
The nozzle’s prints are poor quality or defective.
To replace your nozzle, you need to follow these steps:
Heat the nozzle to the printing temperature of the filament that you used last.
Remove the filament from the extruder and cut off the tip.
Turn off the printer and let the nozzle cool down completely.
Use a wrench or a socket to unscrew the nozzle from the heater block.
Use a new nozzle or a clean nozzle of the same size and material and screw it into the heater block.
Heat the nozzle to the printing temperature of the filament that you want to use next.
Load the filament into the extruder and extrude some filament to prime the nozzle.
Calibrate the nozzle height and the bed level.
Print a test print to check the nozzle’s performance and quality.
