Introduction to 3D Printing The term 3D printing means making a solidifed item or structure by using material which is deposited, joined and solidified under computer control to create a 3 dimensional object. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. Nowdays 3D printing is a part of our life and can be applied in different works. 3D-Printer 3D Printer is a device that can make 3D design or model by laying thin layers of materials. 3D printer is the device to produce very complex shapes or geometries that would be otherwise impossible to construct by hand. Nowdays it is being used in different work of designing models, making facial mask, etc. The term 3D printing means making a solidifed item or structure by using material which is deposited, joined and solidified under computer control to create a 3 dimensional object.
