This project aims to create a way to print useful product and art in wood powder (and other hard organics). This is done with the use of binder jetting, for which I have built a printer years ago called Oasis (https://hackaday.io/project/86954-oasis-3dp). Binder jetting can create products in powder by locally binding the powder with a binder. The great advantage is that the technique can handle all sorts of powders with varying properties.
The goal is to print products completely biodegradable and made of completely renewable resources.
That's an interesting project, but when I first saw the cover picture I thought it was a d*ck pic.
