What is a 3D printer?

A 3D printer is a device that creates a three dimensional model of an object through the process of additive manufacturing. The printer deposits material layer by layer, until the desired object is completed.

Using 3D modeling software, such as AutoCAD or Blender, a designer can create a printable model. 3D printers are primarily used for prototyping, but can also be used for arts and crafts. Like standard printers, the quality of the printer can determine the level of precision that the printer can achieve. Industrial, higher quality versions that produce larger or more detailed objects are called rapid prototyping machines.
