Nowadays, most people can't make anything at home because it's too expensive. Roboticist Hod Lipson wants you to stop shopping and use his portable 3-D printer to make your own stuff. 3-D printing is a universal technology that has the potential to revolutionize our life by enabling individuals to design and manufacture things. Popular Science has done an interview of him about the future of fabbing. Questions include: Q: What sort of things are people printing with your fabber? A: Watchbands, squirt bottles, batteries, artificial muscles, even fancy chocolates. What you print is really up to you. Q: Wouldn't it be cheaper, faster and easier to just go buy a new piece? A: The only way to make something cheaply today is to have it mass-produced. For example, you wear the same shoes as everyone else. If you had a fabber, you could custom-make shoes that perfectly fit your feet. Three-dimensional printing will help us move away from the mass consumption that is so deeply ingrained in our culture.
