Problems solved by technology
The internal cavity of the 3D printed integral sand core will be covered with powder sand particles. After printing, the internal structure of the sand core cavity is complicated, and the powder sand particles are not easy to clean from the cavity. If the sand particles are simply cleaned by compressed air, Then it is difficult to clean the internal sand particles, the cleaning process is time-consuming and laborious, and the cleaning process is more polluting to the environment
