Specific steps of acetone in post-processing of 3D printing resin

in 3D printing technology, resin post-processing is a crucial link, which directly affects the surface quality and performance of printed parts. As a common organic solvent, acetone plays an important role in this process. This article will analyze in detail the specific steps of acetone in the post-processing of 3D printing resin to help readers better understand and apply this technology.

1. Acetone cleaning: remove excess resin

After 3D printing is completed, a layer of uncured resin often remains on the surface of the printed part. These residues not only affect the smoothness of the surface, but may also weaken the strength of the print. At this time, acetone acts as an efficient solvent and can be used to clean these residual resins.

The specific operation steps are as follows:

• Pour acetone into a container deep enough to cover the print.
• Carefully place the print into the acetone solution, ensuring complete immersion.
• Gently shake the container or use a soft brush to lightly brush the print surface to help remove excess resin.
• About 5-10 minutes after soaking, remove the print and rinse with water.

It is important to note that protective gloves and masks should be worn when using acetone to avoid direct contact or inhalation of acetone vapors. Acetone is flammable and should be kept away from fire sources during operation.

2. Acetone soak: Optimize surface properties

In addition to cleaning residual resin, acetone can also be used to further optimize the surface properties of the print. By soaking the print in acetone, the photoinitiator in the photosensitive resin of the surface can be removed, thereby improving the gloss and mechanical properties of the print.

The operation steps are as follows:

• Prepare a closed container and pour the right amount of acetone.
• The cleaned prints were placed in an acetone solution, ensuring complete immersion.
The
• soaking time is generally 30 minutes to 1 hour, and the specific time can be adjusted according to the complexity of the print and the resin type.
When the
• soak is complete, remove the print and wipe the surface with a clean cloth to dry the acetone.

Through this step, the surface of the printed part will be smoother, and its chemical resistance and heat resistance will be enhanced.

3. Acetone polishing: improve surface accuracy

For prints that require a high-precision surface, acetone can also be used in combination with other polishing materials to further enhance the smoothness of the surface. For example, acetone can be combined with fine sandpaper or polishing wax for manual polishing.

Specific operation method:

• A small amount of acetone was poured onto a clean polished plate.
• Use fine sandpaper dipped in acetone, gently polish the printed surface, pay attention to the strength to be uniform, to avoid scratches.
• If you use polishing wax, you can apply the wax evenly on the print surface, and then use a soft cloth to wipe until the surface appears specular gloss.

This method can not only remove fine lines, but also significantly improve the appearance quality of the print.

Conclusion

Acetone is widely used in the post-processing of 3D printing resin, including cleaning residual resin, optimizing surface performance and improving surface accuracy. Each step requires careful operation to ensure the quality and performance of the final print. Through the rational use of acetone, the surface smoothness and mechanical strength of 3D printing parts can be significantly improved, so as to meet higher-level application requirements.
