What Is 3D Printing?Īt its most basic, 3D printing is a manufacturing process in which material is laid down, layer by layer, to form a three-dimensional object. Though still mostly found on shop floors or in design studios, in schools and community centers, and in the hands of hobbyists, 3D printers are increasingly being found on workbenches, in rec rooms, and kitchens-and perhaps in a home near you, if not your own. They're going mainstream, showing up at retailers such as Staples, Best Buy, and Home Depot, and you can buy numerous 3D printers and their supplies on and through other online outlets. As their name suggests, 3D printers can build three-dimensional objects, out of a variety of materials.

In fact, they bear little resemblance to today's document or photo printers, which can only print in boring old two dimensions. They're not your granddad's daisy wheel printer, or your mom's dot matrix.
