3D Printed Luminaires Utilize Waste Coffee Grounds

LumiAdd is a UK-based manufacturer of 3D-printed luminaires. The company has recently pioneered the use of discarded coffee grounds as a raw material for making spotlights and downlights. The waste coffee grounds are combined with polylactic acid (PLA). The company uses plant-based polymers, primarily PLA, to print all of its luminaires.

3D printing on demand dramatically reduces waste. 3D printing in the UK also reduces carbon emissions compared with importing luminaires from Asia. The luminaires are designed to be re-used, repaired and re-manufactured, with recycling or industrial composting being the last option.
