The 3DBenchy is a 3D computer model specifically designed for testing the accuracy and capabilities of 3D printers. The 3DBenchy is described by its creator, Creative Tools, as "the jolly 3D printing torture-test" and was released in April 2015, with a multi-part, multi-color model released in July 2015.

3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together, typically layer by layer.
CAD model used for 3D printing
3D models can be generated from 2D pictures taken at a 3D photo booth.
