3-D printing is the technology that builds products by laying down successive thin layers of plastic, metal, glass, or ceramics. CAM stands for computer-aided manufacturing, which is a broader term that encompasses a variety of manufacturing technologies. STEP is a file format used for exchanging 3D CAD models. Replicators are a fictional device from the futuristic world of Star Trek that can create nearly any object at the press of a button. Virtual reality is a technology that simulates a user's physical presence in a digital environment. None of these technologies have the precise function of 3-D printing.
