3D printing is not a clean process. Sure, it's done on a plate or in a box-like, closed compartment, but there's a lot of waste after every session.
Especially if the thing you print isn't particularly well balanced. It needs a support, a scaffold, a foundation to be built around it, or with it.
That foundation has to be removed after the printing process is finished, and can result in a lot of scraps.
Add to that leftover filament and botched 3D printed objects and there's a lot of wasted material. Made no better by how badly overrun by plastic the world already is.
Add to that the fact that you pay about $40 / €30 for every roll of filament and that amounts to a lot of wasted cash.
15-year-old boy Grayson Galisky believes that he has come up with a viable, ecologically friendly and affordable solution.
Long story short, he has set up a program in which people can donate their scrap plastic, get 1 kg / 2.2 pounds of filament for every 2 kg / 4.4 pounds offered, or send in their scrap plastic in exchange for having it ground up and returned to them. The funding goal will be pretty low, at $4,999 / €3,685, when the Kickstarter campaign goes up.
