Desktop 3D printing has lost its novelty value a bit, but new printing materials that MakerBot plans to release will soon make it a lot more interesting again.

It was a bit lighter than a real hammer but still had some heft to it, and the surface of the wood actually looked and felt like wood grain. It even smelled of wood, because there is real wood in the composite.
