Green 3D Printing - the Solar Sinter

So, I'm sure a number of you out there have heard of 3d printing. I know that while the companies that make them tout some of their "green" capabilities, most of the process of making a 3d model out of resin likely isn't that environmentally friendly.

Therefore, I would like to introduce you to the Solar Sinter. This handy device will turn ordinary sunlight and sand into any shape you would like to hold in your hand, straight from your 3d computer model. The entire process runs from the sun's power, laptop power, device power and object creation. I personally liked his "office". Granted, the final shape isn't super precise, but I would be willing to bet they can refine the process...
