3D printing

variants: or less commonly 3-D printing

Definition of 3D printing

: the manufacturing of solid objects by the deposition of layers of material (such as plastic) in accordance with specifications that are stored and displayed in electronic form as a digital model Whereas traditional manufacturing techniques start with a solid block and cut unwanted material away from it, 3D printing … builds up material in layers, producing precisely the object desired with almost no waste.— Mark Betancourt Imagine dreaming up a toy for your kids, sketching it out on your computer, and minutes later—voilà!—you're holding the real thing in your hand. Such is the promise of 3-D printing, a niche but growing technology that Bre Pettis and his Brooklyn-based start-up, MakerBot, believe will become as common in homes as the printers that crank out our photos and household documents.— Andréa Ford et al.
