This gadget gives a whole new meaning to the word "homemade." Glowforge is a 3D laser printer that creates beautifully designed objects from organic materials such as leather, wood, cardboard—even chocolate. Just like a traditional printer, the Glowforge connects to, and takes orders from, your computer. Instead of loading it with paper, however, you will need to insert the appropriate material for your project of choice, which the printer then cuts into perfectly measured pieces. All you need to do is assembly and enjoy. Available for preorder at Glowforge.com; 5,995 for the pro model.
