Over the past few years, <\/span>Signify<\/a> (formerly Philips Lighting) has helped illuminate several locations in Copenhagen \u2013 including the City of Copenhagen \u2013 with its 3D-printed luminaires. 3D mass production enables both large-scale customised production and more sustainable manufacturing.<\/span><\/p>\n

Thousands of lamps light up buildings owned by the City of Copenhagen every day. And the light is housed in 3D-printed luminaires from the Dutch company Signify (formerly known as Philips Lighting), which over the past four years has delivered more than 3,000 3D-printed luminaires to the City of Copenhagen. All as part of a desire for more sustainable environments. <\/p>\n

\u201cProducing traditionally manufactured luminaires takes longer and is more complex at scale. With 3D printing technology, we have less waste, use less material, we can produce on demand, and we are closer to customers in both the design phase and production, because we can easily set up large-scale production anywhere in the world,\u201d says Signify Business Manager Emma de Looff: <\/p>\n

\u201cSustainability is at the core of our work and business, and 3D printing technology is a game changer for our industry. We only produce what we need, in a fast and efficient way.\u201d <\/p>\n<\/div><\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n

The sustainable aspect of Signify\u2019s luminaires is primarily about the material-polycarbonate filament, which is a strong, high-quality material-and the printed plastic can be recycled through re-granulation at end of life. According to Signify, a 3D-printed polycarbonate lamp has a 47% lower CO2 footprint than a traditionally manufactured metal lamp. In addition, there is no glue and fewer parts, and the lower weight saves 35% CO2 in transport. <\/p>\n

\u201cThe lamps are more sustainable for three reasons. First, the material is lighter, which reduces the transport CO2 footprint, and we do not powder-coat the material. Second, the design uses as few components as possible and no glue, making the product, components and materials easier to recycle,\u201d says Emma de Looff from the headquarters in the Netherlands, which-like the Nordic headquarters in \u00d8restaden-is fitted with 3D-printed luminaires: <\/p>\n

\u201cAnd third, AM technology makes it easy to establish factories locally and thus be close to our customers, reducing the number and distance of logistical movements in the supply chain.\u201d<\/p>\n<\/div><\/div>\r\n<\/div>\r\n\r\n

Even new products that you can design yourself. In the future, Signify will offer consumers the opportunity to leverage the major design advantages of AM technology by letting them design their own pendant or table lamp online, with countless options for size, colour, texture and pattern. Signify will then 3D-print it in recyclable materials and deliver it to their door within a few weeks. The first lamps are made from 24 old CDs, and everything except the E27 socket and the light source is 3D-printed. <\/p>\n

\u201cBut we are also exploring the potential of making lamps from old fishing nets pulled from our oceans. We want to push the boundaries when it comes to design, and for us, recycling materials is just one of the ways we can support a sustainable and more circular economy,\u201d says Emma de Looff, echoed by an enthusiastic Managing Director of Dansk AM Hub: <\/p>\n

\u201cSignify has discovered how AM and 3D printing create entirely new opportunities to design, develop and produce the products of the future. We hope this can inspire many more companies to challenge traditional manufacturing thinking with new technology such as AM,\u201d says Frank Rosengreen Lorenzen. <\/p>\n<\/div><\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n
