3D printing (or additive manufacturing, AM) is any of various processes used to make a three-dimensional object.in year 1984, Chuck Hull of 3D Systems Corporation, developed a prototype.

The earliest 3D printing technologies first became visible in the late 1980’s, at which time they were called Rapid Prototyping (RP) technologies. This is because the processes were originally conceived as a fast and more cost-effective method for creating prototypes for product development within industry.
