What is the difference between 3D printing and rapid prototyping?

Due to evolution, different product development methods like 3D printing and rapid prototyping have taken birth. 
Both rapid prototyping and 3D printing are put to use in additive manufacturing. Some people have confusion between both the technologies and consider the same. 
Let’s clear your confusion
Additive manufacturing 
Additive manufacturing is the technique where the addition of materials takes place layer by layer to form a 3D object. Thus the term “Additive” refers to the addition.

3D Printing 
In the 3D printing process formation of 3D objects takes place from the digital mock-up. Formation of the item takes place utilizing nozzle, print head, and printing machine. 
Rapid Prototyping
Rapid prototyping is the method through which the creation of the model takes place at a faster pace. But for the creation of the object additive manufacturing and 3D printing are put to use.
