In 3D Laser cutting, the part to be cut needs to be positioned and held in the working area of the machine in a repeatable way. One must use some kind a support to achieve this objective. Such supports are known as fixtures, reference fixtures or fixing gauge. 

These supports can be fabricated in different ways. They support the workpiece by copying the contour shape of the tridimensional part to be cut. In this way, the part can be easily positioned and fixed for cutting. The fixture also must make sure that the part does not move during the cutting process.

The different types of supports exist not only because of different types of parts that are to be cut but also because of different production volumes to be produced.
