The Hikarigami lighting project presents a series of luminaires formed from flat aluminum sheets using robotic fabrication techniques. Developed by a Harvard GSD team, each piece is shaped through single-point incremental forming, where a robotic arm presses into the material with precise, programmed movements. The resulting surfaces feature intricate perforated patterns that vary in density and geometry, producing panels that function as both structure and ornament. Each unit is composed of multiple facets that come together to form a geometric enclosure.
When illuminated, the panels act as both diffuser and lens, casting shifting light patterns across surrounding surfaces. The aluminum retains visible marks from the forming process, including grain direction and subtle irregularities created during fabrication. These surface conditions remain present in the final object, alongside the cut patterns that define how light passes through each panel. The project was completed in 2025 by a team specializing in computational design and robotic fabrication.

Hikarigami Lighting Explores Aluminum Forming and Light Projection
Trend Themes
1. Robotic Incremental Forming - Precise, single-point robotic deformation of sheet metal enables complex, low-waste geometries that challenge traditional stamping and die-based production methods.
2. Perforated Light-surface Integration - Luminaires that combine structural panels with patterned cutouts create programmable light diffusion and projection effects that redefine how surfaces communicate spatial information.
3. Material-finish Authenticity - Retention of forming marks and subtle irregularities foregrounds the aesthetic value of process-visible surfaces, shifting consumer preference toward traceable, craft-inflected industrial objects.
Industry Implications
1. Architectural Lighting - Customizable aluminum panels that act as both structure and optic open possibilities for integrated façade and interior lighting systems with dynamic patterning.
2. Custom Furniture and Fixtures - Facet-based enclosures formed by robotic shaping support bespoke, geometric furniture and fixture pieces that emphasize process-derived surface character.
3. Advanced Manufacturing Tooling - Programmable single-point forming workflows suggest new tooling ecosystems and software services for on-demand, low-volume metal part production.
