As 3D printing technology becomes increasingly popular, the post-processing process of 3D printed parts plays a vital role in improving the quality and performance of printed parts. Among them, sandblasting is a commonly used post-processing method for 3D printed parts. It is a process that processes the surface of parts by spraying sand particles at high speed. It can effectively improve the roughness of the surface of parts, remove defects and enhance their mechanical properties. Its basic operations are as follows:
1. Preliminary preparation:
Choose suitable sandblasting equipment and abrasives, and ensure a safe working environment.
2. Fix the parts:
Fix the 3D printed parts on the workbench of the sandblasting equipment to prevent them from moving during the sandblasting process.
3. Select parameters:
Choose appropriate parameters such as sandblasting pressure, sandblasting time and abrasive particle size according to the material and requirements of the parts.
4. Start sandblasting:
Start the sandblasting equipment and spray the abrasive onto the surface of the parts. During the sandblasting process, keep the distance and angle between the spray gun and the surface of the parts consistent to ensure the consistency of the sandblasting effect.
5. Check the effect:
After the sandblasting is completed, check the quality and roughness of the part surface. If necessary, perform multiple sandblasting or adjust the parameters until the required effect is achieved.
6. Cleaning:
Remove the sandblasted parts from the workbench and clean them to remove residual abrasives and impurities such as dust on the surface.
7. Quality inspection:
Perform quality inspection on the sandblasted parts to ensure that they meet relevant standards and requirements.
8. Post-processing:
Finally, the sandblasted parts can be post-processed as needed, such as painting, electroplating, etc., to improve their corrosion resistance and aesthetics.
The sandblasting process of 3D printed parts is a systematic and rigorous process. Each operation link has an important impact on the quality and performance of the final parts. Only by mastering and strictly following the basic operation process of the sandblasting process can the advantages of the sandblasting process be fully utilized and a strong quality guarantee can be provided for the widespread application of 3D printed parts.
