The entire creation process was a learning journey, presenting challenges not only in surface modeling but also in physical fabrication. Prior to this, we had rarely worked with free-form surfaces—an intriguing challenge that required balancing both aesthetics and structural stability.
In practical design, partitioning models had never been particularly difficult for me. However, I discovered that when it comes to surface modeling, the complexity of partitioning increases significantly. Fortunately, we quickly identified solutions. Considerations for tolerance issues were also particularly important: due to excessive curvature in certain areas, several problems emerged in the 3D-printed parts, such as:
- Collapsed bridging over holes
- Excessive support material leading to rough surfaces
- Difficulties in support removal
- Interference fits between components
These issues can largely be optimized by adjusting printing parameters in the slicing software. One problem remains: for the assembly of the pumpkin lamp, I initially chose 3mm diameter, 2mm thick magnets to allow each component to rotate to different angles for varied display effects. However, during actual assembly, it became apparent that magnets of this size provide insufficient magnetic force, making a peg-and-socket structure more effective.
