How can you adjust the printing temperature for wood filament?

1 Why temperature matters

The printing temperature for wood filament depends on several factors, such as the type and ratio of wood fibers, the base material (PLA or ABS), the nozzle size, the layer height, and the printing speed. Generally, wood filament needs a higher temperature than regular PLA or ABS, because the wood fibers create more friction and resistance in the extruder. A higher temperature also helps to melt the wood fibers and create a smoother and more consistent flow. However, too high a temperature can cause the wood fibers to burn and clog the nozzle, or create a dark and brittle print.

2 How to find the ideal temperature

The ideal temperature for wood filament varies from brand to brand, and even from batch to batch, so it is important to do some test prints and experiments before starting a large or complex project. A good way to find the ideal temperature is to use a temperature tower, which is a 3D model that prints at different temperatures along its height. You can download a temperature tower from online repositories, or create your own using a slicer software. A temperature tower allows you to compare the quality and appearance of the print at different temperatures, and choose the one that suits your preferences and needs.

3 How to avoid nozzle clogs

One of the most common problems when printing with wood filament is nozzle clogs, which can ruin your print and damage your 3D printer. To avoid nozzle clogs, you should use a larger nozzle size, such as 0.4 mm or 0.5 mm, which can handle the wood fibers better than a smaller nozzle. You should also clean your nozzle regularly, especially after printing with wood filament, using a needle or a wire brush. Another tip is to use a cold pull technique, which involves heating up the nozzle, inserting a piece of filament, cooling down the nozzle, and then pulling out the filament with a quick motion. This can help to remove any residue or debris from the nozzle.

4 How to prevent stringing and oozing

Another issue that can affect the quality of your 3D prints with wood filament is stringing and oozing, which are thin strands or blobs of filament that appear between the parts of your model. Stringing and oozing are caused by the filament leaking from the nozzle when the extruder moves from one point to another. To prevent stringing and oozing, you should reduce the printing temperature, as well as the retraction distance and speed. Retraction is a feature that pulls back the filament from the nozzle when the extruder moves, to prevent leaking. You can adjust the retraction settings in your slicer software, and test different values until you find the optimal ones.

5 How to enhance the wood effect

One of the advantages of printing with wood filament is that you can create a realistic and natural wood effect, by using different techniques and post-processing methods. For example, you can vary the printing temperature during the print, to create different shades and contrasts in the wood fibers. You can do this manually, by changing the temperature on your 3D printer, or automatically, by using a plugin or a script in your slicer software. Another technique is to sand, stain, or paint your 3D prints, to give them a smoother and more refined finish. You can also use a heat gun, a torch, or a soldering iron, to create a burned or charred effect on the surface of your 3D prints.

6 How to store and handle wood filament

Wood filament is a hygroscopic material, which means that it absorbs moisture from the air, and this can affect its printing performance and quality. To store and handle wood filament properly, you should keep it in a sealed bag or container, with some silica gel or desiccant packets, to keep it dry and prevent it from becoming brittle or swollen. You should also avoid exposing it to direct sunlight or heat sources, as this can degrade its color and texture. If you suspect that your wood filament has absorbed too much moisture, you can dry it in an oven, at a low temperature and for a short time, before using it.
