If you are a fan of 3D printers and 3D printing, and at the same time you try to be environmentally friendly, then you will certainly be pleased with the news from 3D Systems. 
That there are printers on which you can model and then print three-dimensional objects according to your wishes is known to every designer, graphic artist, modeler, or person who has even a little technical knowledge. However, development is constantly moving forward. The American company 3D Systems has developed the EkoCycle Cube 3D printer, which, as its name suggests, can print from waste plastic and thereby recycle it. Plastic waste does not end up in a landfill but is ecologically melted down into a new product, whether practically usable or artistic. From an ordinary plastic bottle, toys, bowls, household items, stylish jewelry, or even a birdhouse can be created – see for yourself in this video demonstration. The imagination knows no bounds.
