3D printing technology has been widely used in various fields in recent years, and the use of Wood filament for printing is also gradually popular. However, after printing is completed, the surface of the model usually has some flaws and rough parts, which need to be improved by post-processing to improve its appearance and performance.

First, after removing the print from the 3D printer, a preliminary cleaning work is required.

Since Wood filament may produce some debris and excess powder during printing, the surface of the model can be lightly cleaned using compressed air or a soft brush. This step not only removes impurities from the surface, but also makes subsequent treatment more convenient and efficient.

The next step is to remove the support structure.

During the printing process, the support structures are set up to prevent the model from collapsing in the hanging part, but they leave traces on the surface of the model. Using a tool such as diagonal pliers or a scalpel, the support structure can be carefully cut away. For some small residual support, you can use a pen knife to gently scrape off, pay attention to moderate strength, so as not to damage the surface of the model.

After the removal of the support, grinding is an important step to improve the surface quality of the model.

For models printed with Wood filament, sandpaper with different mesh numbers can be used to sand, starting with low mesh numbers (such as 400 mesh) and gradually increasing to high mesh numbers (such as 1200 mesh or more). Sanding should be done with water, which can prevent the material from overheating and fuzzing, while making the sanding effect more uniform.

After grinding, if you need to further improve the surface smoothness of the model, chemical polishing can be used.

Chemical polishing of Wood filament usually uses some specific solvent, such as acetone or special wood polishing liquid. These solvents dissolve tiny bumps on the surface of the model, making it smoother. During operation, the model is suspended in a well-ventilated environment and the surface of the model is fumigated with solvent steam, taking care that the time should not be too long to avoid excessive corrosion.

For some models that require higher surface quality, sandblasting is a good option.

Sandblasting The surface of the model is polished by spraying fine abrades (such as glass beads or alumina) at high speed, which can achieve a very uniform and smooth effect. Sandblasting is usually done in a closed chamber and is easy and quick to operate, usually within 5 to 10 minutes.

In addition to surface treatment, coloring is also an important step to enhance the beauty of the model.

Wood filament printed models can be painted by hand or spray paint. Manual coloring is suitable for dealing with complex details, and the operation needs to be flat painted two to three times in the "#" shape to make the color uniform and full. The spray painting rule applies to the overall color, the model needs to be polished and sprayed with primer before operation, then sprayed with top paint, and finally sprayed with a layer of gloss or matte paint to achieve the desired effect.

Finally, for some large or complex models, it may be necessary to split them into multiple parts for printing and then glue them together.

It is best to apply glue in a point way and fix it with a rubber ring to ensure tight adhesion. If the bonding process encounters gaps in the model or rough contact, you can use Bondo glue or filler to smooth it out.

To sum up, the post-processing of Wood filament in 3D printing includes steps such as cleaning, support removal, sanding, chemical polishing, sandblasting, coloring and bonding assembly. Through these meticulous treatments, the appearance and performance of the model can be significantly improved, bringing it closer to the finished product of the design.
