Eureka's River Luminaire Leverages Large-Format 3D Printing for Decorative Lighting

Montreal-based lighting manufacturer Eureka, part of Acuity Brands, has launched the River Luminaire series, a collection of 13 decorative lighting fixtures. This marks Eureka's first use of large-format additive manufacturing (LFAM) in its product line, collaborating with Florida-based Haddy to create shapes and textures not achievable with traditional methods.

The collection comprises six distinct form families: linear, square, oblong, ring, lagoon, and freeform, offering a diverse range of options for various environments. All thirteen fixtures share a common construction: a translucent polymer body manufactured via robotic LFAM processes. The visible layering from the 3D printing process is intentionally incorporated as a design element, creating a subtle interplay of light and shadow when the internal LED is illuminated.

Further enhancing their versatility, the fixtures offer modular mounting options. Customers can choose between pendant mounting, suspended by aircraft cables for a floating, sculptural appearance, or surface mounting for a softer, ambient light effect. Selectable metal bracket finishes allow for seamless integration into hospitality, corporate, and civic interiors, suitable for spaces ranging from food courts and amenity areas to boardrooms and reception lobbies.

The partnership with Haddy, located in St. Petersburg, Florida, was crucial for this development. Haddy operates a microfactory equipped with CEAD Flexbot robotic LFAM systems, featuring AI-assisted platforms and integrated milling capabilities. The company has a proven track record in various sectors, including producing Unmanned Surface Vessels, fabricating props for Disney theme parks, and bringing 3D printed vases to retail.

For Eureka, the adoption of LFAM provided two key benefits: the capacity to produce complex, organic geometries at scale and significantly reduced development cycles. According to Haddy, "Working with Acuity Brands and now featured by Eureka Lighting, these fixtures represent an important milestone for Haddy’s lighting segment and demonstrate how large-format additive manufacturing is creating new opportunities within the lighting industry."
