3D printing is coming off the ground, more and more this technology is used for larger quantities and with that, the environmental impact is increasing. We at Signify are producing luminaires based on 3D printing already in large quantities and this will increase further in the coming years. We would like to use, instead of the current plastics, new materials with a bio origin. The challenge is that besides this origin. the materials have to fulfil certain requirements like temperature resistance, strength, reliability etc.
