Zhong, Wade-Giles romanization Chung, Chinese clapperless bronze bells produced mainly during the late Zhou (c. 600鈥255 BC) dynasty and used as a percussion instrument in ancient China.
Dalian MSA ordered a giant bell model to be presented in the hall of their office building. They required the bell to have some embossment of their badges, poems, totems, the Eight Diagrams, etc. Those intricate characters and patterns increased the difficulty in post-processing.
We printed the bell with FDM 3D printers using PLA filament. It was so large that we had to break down the model and print each part separately. We painted the bell using bronze-like colors and added black color to make it look older.
Solution
Step 1: Our designer drew some drafts, communicated with the customer, and made revisions until both were satisfied.
Step 2: 3D modeling of the bell, adjusted the height of those embossments to make them noticeable.
Step 3: Slicing the model and break it into several parts.
Step 4: 3D printing the bell with FDM 3D printers using PLA filaments.
Step 5: Sandblasting, polishing, and painting. The fine painting process is time-consuming as the aging process really needs patience.
