Transforming a Symbol of Unity into a Precision-Engineered Reality

Large-scale international sporting events demand more than performance—they require symbolism, precision, and flawless execution. When organizers of a recent Asian multi-sport event in China sought to produce their official torch, they turned to advanced manufacturing technologies to meet both aesthetic and functional demands.

At DG Proto, we supported the development of critical torch components using high-performance 3D printing prototyping services, enabling rapid iteration, complex geometry realization, and tight production timelines.

Client Challenge

The event organizer and design team faced several key challenges:

• Complex Geometry
  The torch featured intricate curves and hollow internal structures inspired by traditional Chinese cultural elements.
• Lightweight but Durable
  It needed to be lightweight for runners while maintaining structural strength and heat resistance.
• Short Development Timeline
  Design validation and functional testing had to be completed within a compressed schedule.
• High Surface Quality Requirements
  The torch required a premium finish suitable for global broadcast and close-up media exposure.

Our Solution

DG Proto utilized a combination of advanced 3D printing technologies and post-processing techniques to deliver a reliable solution.

1. Rapid Prototyping with Industrial 3D Printing

We employed high-resolution additive manufacturing to quickly produce multiple design iterations:

• SLA printing for high-detail surface validation
• SLS printing for structural testing
• Metal 3D printing for heat-resistant components

This allowed the design team to evaluate ergonomics, balance, and internal airflow efficiently.

2. Lightweight Structural Optimization

Using topology optimization and lattice structures, we reduced weight while maintaining strength:

• Optimized internal channels for airflow and combustion
• Reduced material usage without compromising durability
• Improved handling comfort for torchbearers

3. Precision Surface Finishing

To meet the visual standards of an international event, we applied advanced finishing processes:

• Sandblasting for uniform texture
• Polishing for reflective metallic surfaces
• Coating and anodizing for durability and aesthetics

The final result achieved a premium, camera-ready appearance.

4. Fast Turnaround & Engineering Support

Our engineering team worked closely with designers to accelerate development:

• Real-time design feedback
• DFM (Design for Manufacturing) optimization
• Rapid iteration cycles within days instead of weeks

Results

• 50% Reduction in Development Time
• Multiple Design Iterations Completed Within Days
• Weight Reduced by 30% Compared to Traditional Manufacturing
• High-Precision Components with Excellent Surface Finish

The final torch successfully met all functional and visual requirements, contributing to a memorable global event.

Why 3D Printing Was the Right Choice

This project highlights the advantages of additive manufacturing for complex, high-visibility applications:

• Freedom of design for complex geometries
• Faster prototyping and iteration
• Reduced tooling costs
• Efficient low-volume production

Conclusion

From concept to final product, 3D printing enabled a seamless transition from artistic vision to functional reality. For high-profile projects where precision, speed, and design complexity matter, additive manufacturing proves to be an essential solution.

At DG Proto, we continue to help clients bring ambitious ideas to life with advanced 3D printing prototyping services.
