Additive manufacturing , also known as incremental production , is a device that produces computer- designed or 3D modeled designs quickly , without the need for an extra mold , using various materials ( varies according to the part to be produced). These devices , besides the main sectors such as machinery, agriculture, automotive, medical , toys, stationery , etc. in terms of practicality of use and cost-effectiveness . Its use has become widespread in many sub- sectors .

The basic working logic of the 3D printer is based on the direct production of any three- dimensional model by melting the plastic with layering technology . In order to better understand the basic working logic of the 3D printer , it is possible to collect them under 3 headings;
