3D printing, otherwise known as additive manufacturing, is a manufacturing process that builds a part layer by layer. A computer sends instructions to the 3D printer, which deposits or hardens material in a preprogrammed pattern, creating layers in succession.
There are several kinds of 3D printer, some of which are used to print plastic parts, others to print parts made from metal or other materials. While these various 3D printing technologies are diverse, they have certain features in common.
3D printing has revolutionized manufacturing by giving businesses access to a one-step manufacturing technology. 3D printers can be set up in offices and small workspaces, and require minimal training to operate. Moreover, startup costs are incredibly low, since materials are affordable and can be purchased in small quantities.
