What is the difference between additive manufacturing and 3D printing?

Some people use 3D printing and additive manufacturing (AM) as interchangeable terms, although 3D printing is only one example of an AM method. 3D printing refers to the process of using a three-dimensional digital model to join or solidify the material, frequently using a moving platform to deposit and fuse material. Additive manufacturing is a broader process, and its systems don't always resemble printing. For example, additive manufacturing is used in the food industry to create chocolates, candies, and even pizzas. An additive manufacturing engineer is responsible for developing AM processes and procedures, often deciding which materials to layer, helping with research and development, designing tools, and designing model production processes.
