Design Demonstrations
During the workshop, the instructor demonstrated the design and printing of various objects, ranging from simple geometric shapes to functional prototypes like phone stands and mechanical parts. One of my personal projects was designing a custom battery clip for my robot, which required careful consideration of dimensions, flexibility, and secure mounting. Challenges such as optimizing support structures and balancing print speed with quality were discussed. These demonstrations highlighted key considerations in 3D printing workflows.
Technical Insights and Troubleshooting
The workshop covered common technical challenges including adhesion failures, warping, and layer misalignment. Participants learned troubleshooting strategies such as adjusting bed leveling, modifying print settings, and experimenting with different materials. The instructor shared professional tips for diagnosing and resolving print errors.
Common Issues and Solutions:
- Improving bed adhesion using glue sticks and heated beds
- Addressing layer separation by optimizing print temperature and speed
- Designing effective support structures to minimize material waste
- Mitigating warping through enclosure use and proper cooling
