If you live in San Francisco, you may have seen the ads pasted around town over the last few years touting images of slick, 3D-printed lamps that promise functionality and form without costing a fortune. The culprit? Gantri, a startup that collaborates with innovative designers to bring sustainably-produced, high quality lighting to the market. Gantri is unique in that they use digital manufacturing to cut down on waste and keep prices low for the thrifty, design-minded consumer. All of their lighting products are 3D-printed using a custom blend of plant-based PLAs. On top of all that, all their lights are produced on-demand in a sustainable factory in San Leandro, California.

Gantri tapped San Francisco–based Ammunition to design three new collections: Gio, Signal, and Carve. The results are intricate, organic, and unexpected forms that reflect the brand’s commitment to radical design.

“Ammunition has an incredible reputation for creating thoughtful, beautifully crafted products that inspire both consumers and designers. We were thrilled to bring the studio’s process and philosophy to the Gantri platform with lighting collections that offer an amazing level of quality, detail, and expression.”
—Gantri founder and CEO Ian Yang

The Gio Collection

The Gio Collection is inspired by Italian lighting designs of the 1970s that sought to remake and refresh historic archetypes through new materials and processes. The unique character of the Gio Collection came to life by manipulating and rationalizing classical geometric elements so they interact with each other in playful ways. The elegant shapes connect and merge seamlessly, with a material presence and character found commonly in crafted ceramic objects. The familiar yet uncommon forms give the lamps sculptural qualities that stand alone as interesting objects even when they are not illuminated.

The Signal Collection

The Signal Collection features louvered slats that are fused to the main body of each light through the 3D printing process. The slats were inspired by the functional aspects of exterior architectural louvers used to bring light and air inside. Here, the slats allow light to be directed intentionally, while bringing a softer feel to spaces. The simple geometry of the floor, wall, and table lights combined with the bold louver pattern gives the collection a look that is somehow both friendly and modern.

The Carve Collection

The Carve Collection’s monolithic forms and seamless surfaces feel carved from stone rather than assembled like conventionally manufactured objects. Standing upright, the collection’s table light casts a wide, bright light to illuminate work surfaces or tasks. And when placed on its spine, it can cast light upward to create ambience through reflected light. The smooth form of Carve’s pair of wall lights contribute only a subtle ripple to wall surfaces while casting targeted light. A tall and narrow floor light rounds out the collection by producing a surprisingly bright downward beam it spite of its compact footprint and shade.
