Project Background
Our client, a high-end interior design firm, approached REBAN with a concept for a series of intricate decorative spheres featuring a “hollow-out” lattice design. These spheres were intended for a luxury commercial installation where aesthetic precision and environmental stability were paramount.
Traditional manufacturing methods, such as CNC machining or injection molding, were deemed impossible due to the deep internal features and the “undercuts” of the spherical lattice. On May 20th, 2025, the client sought a manufacturing partner capable of producing 10 identical, high-resolution pieces within an aggressive 3-day window for a project unveiling.
Project Challenges
Geometric Complexity: The hollow-sphere design featured overlapping internal lattices that standard rotating cutters could not reach.
Material Stability: Decorative pieces in public spaces must withstand humidity fluctuations. The client needed a material that wouldn’t “weep” or warp over time.
Surface Uniformity: Because the spheres were decorative, every visible surface—including the thin internal struts—needed to be smooth and free of printing artifacts.
REBAN’s Professional Solution
1. High-Performance Resin: Somos 14120
To ensure the longevity of the installation, we selected Somos 14120, a premium white ABS-like resin. Its standout feature is its extremely high water and moisture resistance, ensuring the spheres maintain their dimensional accuracy and crisp white color even in variable environments.
2. SLA Additive Excellence
Utilizing industrial-grade SLA technology, we bypassed the limitations of traditional hard tooling. The laser-based curing process allowed us to build the complex internal features and thin-walled hollow structures directly from the CAD file, achieving a level of detail that is impossible with conventional manufacturing.
3. Expert Manual Sanding
After the 3D printing process, each of the 10 spheres underwent meticulous manual sanding. Our technicians carefully smoothed the outer shell and accessible lattice points to ensure a premium, uniform matte finish that highlighted the intricate geometry of the design.
4. Rapid Iteration & Production
By eliminating the need for expensive mold investments, REBAN moved the project from design review to final print in hours. Our streamlined 3D printing workflow allowed us to deliver the complete batch of 10 pieces within the 3-day deadline.
Results & Customer Benefits
Cost-Effective Complexity: Achieved highly complex geometric features without the need for expensive injection molding tools.
Zero Design Compromise: The client was able to realize their original vision of a seamless, hollow lattice that would be unmanufacturable by other means.
Fast-Track Delivery: The 3-day lead time allowed the client to meet their installation schedule with zero delays.
Successful Collaboration and Future Plans with REBAN
Upon receiving the decorative models, the client shared their satisfaction: “The level of detail REBAN achieved in these hollow spheres is breathtaking. We were worried about the fragility and the finish, but the parts are sturdy and look like high-end molded products. Amazing work!”
