One of the biggest impediments to progress in the 3D-printing space is finding reliable and renewable sources for filament — the material used to print objects — but the Ekocycle Cube 3D Printer uses filament made partially from post-consumer PLA like that found in plastic bottles. This lets you create incredible, unique works of art and everyday items from stuff people frequently just throw away. You can design and print objects on this 3D printer using the included smartphone app, or choose from a number of already-existing designs. Either way you're contributing to the growing maker culture, while keeping your impact on the planet at a minimum. That sounds like a win-win.
