Signify opens world's largest 3D-printed lighting factory in Piła, Poland with 100 printers, scaling to 300 by year-end

Signify has opened what it claims is the world's largest factory dedicated to 3D-printed lighting solutions in Piła, Poland. The facility currently operates 100 3D printers, with plans to scale to over 300 by the end of 2026. The plant integrates additive manufacturing, material preparation, post-processing, and assembly under one roof, producing over 10,000 luminaires per month for European markets with a five-day turnaround from order to shipment. The factory operates under Signify's Circle initiative, using materials composed of at least 75% recycled and bio-based content, and is part of the company's "Brighter Lives, Better World 2030" sustainability program targeting a rise in circular-product revenue from 10% to 27.5% by 2030.

This expansion represents a rare instance of a major industrial OEM committing to serial production AM at scale outside of aerospace or medical, and it validates polymer-based additive manufacturing as a viable production tool for high-volume, mass-customized consumer and commercial goods. Signify is effectively using AM to invert the traditional lighting supply chain—moving from centralized mass production of standardized fixtures to localized, on-demand manufacturing of customized luminaires. The move directly addresses the tension between inventory risk and customer demand for variety, a problem that has historically limited AM adoption in the broader industrial-tooling and consumer-facing segments. The Piła site joins Signify's global AM network spanning Littlestown (Pennsylvania), Peachtree (Georgia), Sydney, and its development center in Eindhoven, creating a distributed production footprint that mirrors the service-based adoption pattern seen in metal AM but applied to polymer-based end-use parts.

For the AM industry, the practical takeaway is that Signify has built a repeatable factory model—not just a demo cell—and is now scaling it. The key execution challenge will be maintaining material consistency and quality across the planned 300-machine fleet while keeping the five-day lead time intact. For buyers and specifiers in commercial lighting, this means Signify can now offer customized luminaire geometries with lead times that undercut traditional injection-molded supply chains, particularly for mid-volume runs where tooling costs are prohibitive. The real test will be whether this model achieves the targeted 27.5% circular-revenue share by 2030 without compromising margin.
