Transforming Materials with Visionary Design

The mid-career retrospective of design studio Rael San Fratello, titled the “rael san fratello exhibition,” at San Francisco’s Yerba Buena Center for the Arts highlights the studio’s innovative use of bio-based thermoplastics and recycled broom heads. Founded in 2002 by Virginia San Fratello and Ronald Rael, the Oakland-based studio’s work spans structures, objects, models, and films.

“Sanctuary”: A Centerpiece of Tradition and Innovation

A notable exhibit is “Sanctuary,” a cylindrical structure 3D-printed with soil, straw, and water, featuring a mirrored inflatable orb. Visitors can step inside to experience this blend of ancient and futuristic elements. This piece stands out in the exhibit for its unique take on merging tradition with innovation.

“Made from the oldest building material using modern robots,” the studio highlights the innovative craft that showcases 3D printing technology.
