3D printing is a process by which three-dimensional objects are created by joining or solidifying materials and combining them layer by layer, depending on the commands of a computer. 3D printing is becoming increasingly popular in many fields, this is why it is now commonly used by both professionals and amateurs.

3D printing is an innovative process by which a digital model is transformed into a tangible, solid, three-dimensional object. Usually, this is done by laying several successive, thin layers of a material.

3D printing has become so popular in recent years because it offers real support in production. This is, on one hand, due to the affordable price, and, on the other hand, to the small size of the printers compared to classic production.
