3D printing

In general, 3D printing technology allows us to create an object of almost any shape. The technology evolved from ink-jet printing: melted plastic (instead of ink) is sprayed layer by layer according to the instruction file and becomes solid at room temperature. Besides the mentioned way of 3D printing, there are several other technologies that allow customers to produce parts of different materials such as metal, concrete, rubber, etc.

For example, in the special 3D printing technique to produce metal parts the metal object is generated in the sand dust; the metal is melted into a solid object heated by a laser.
