The task was to develop a parametric surface pattern using simple geometric elements. I started with circular rings featuring recessed centers, chosen for their clarity, symmetry, and reproducibility. My original aim was to explore structured repetition while introducing variation through systematic design rules. Using sequencing, rotation, and scaling, I created a pattern with visual rhythm and hierarchical order. The design was modeled digitally with precision and prepared for laser cutting. Throughout the process, the pattern evolved through testing and iteration, balancing rule-based structure with visual interest. The parametric approach enables reproducibility, flexibility, and precise control—making the pattern both functional and decorative. It can be adapted to different materials or sizes while maintaining its internal logic and aesthetic coherence.
Making a Grid
The project began by constructing a dodecahedron in Rhino3D, starting with a single pentagon. I mirrored the pentagon multiple times to form a bowl-like structure, then mirrored that half to complete the solid. After creating the full form, I unrolled the 3D geometry into a flat layout, which provided a modular grid across the surface. This grid served as the foundation for applying my pattern, which consists of circular rings with recessed centers. The pattern was developed using sequencing, rotation, and scaling to create rhythm and visual hierarchy. The result is a parametric system that is both structured and adaptable. The combination of precise geometry and rule-based variation makes the design suitable for laser cutting and surface applications.
First Laser-Tests
During the first laser cutting tests, I encountered problems where some circles were placed too close together, causing fragile sections to break off completely. I had created several different patterns, and the one with the flower design was the most fragile due to its intricate and delicate details. For my pattern idea to fully work, I would have needed more space than I had available because the pieces would otherwise become too fragile. To address the issues in the circle design, I increased the gaps between the circles and ensured more clearance near the edges. These adjustments improved the structural integrity of the cuts, preventing breakage while maintaining the overall pattern’s visual rhythm. The iterative process highlighted the importance of balancing detailed design with fabrication constraints, ultimately resulting in a more robust and manufacturable template.
Second time´s the charm
The second time around, everything worked out fine. The pattern had enough space between the circles, allowing the laser cuts to come out clean and intact. After the successful cuts, I assembled the pieces into the dodecahedronic form and carefully glued the sides together. This final step brought the digital design into a tangible, stable structure, demonstrating the effectiveness of the adjusted pattern.
