*Okay, they don't say that it *performs* like wood – just that it *smells* like wood, and has some vaguely wooden behaviors. Basically, it's recycled sawdust with glue.
*Still, that's messed-up.

"LAYWOO-D3 is a new filament for 3D printers created by Thingiverse member Kaipa, which is made of 40% recycled wood held together with polymer binders. It could open up a new realm of possibilities for 3D printing and furniture making. The 3mm zero-warp filament, designed for RepRap 3D Printers and similiar, produces items that look and smell like wood."
