3D printer table lamp Koral - made from recycled PET bottles In addition to its attractive appearance and lighting effect, the Koral table lamp from Tagwerk has two other important aspects to offer: Firstly, it is made in Germany and secondly, it is made from a material for which old PET bottles have been used. This material can be recycled at the end of its service life and returned to the industrial cycle. Otherwise, the so-called PETG material is just as durable as conventional material used to make decorative objects and is also heat-resistant up to 80 degrees C. The production of these special lamps is carried out in a 3D printer. According to the company name, it takes one day to produce such a light and complete the "Tagwerk". Die production generates no waste and no noise pollution. The electricity required is generated from renewable energies.
