Depending on the underlying concept, manufacturing technologies are broadly divided into four groups: additive, subtractive, formative and hybrid.[1]

Additive manufacturing

Additive manufacturing (AM) is a process whereby an object is constructed through depositing material in a controlled manner, layer by layer, until a full object is achieved. 3D printing processes are based on the concept of additive manufacturing.

Subtractive manufacturing

Formative manufacturing

In most formative processes, a liquid is poured into a cavity, taking the cavity's shape as it hardens. Examples include different types of molding, forming and casting.

Formative techniques such as injection molding are often used when a high volume of parts are produced, because fabricating the molds takes a high initial investment, but this mold can then be reused over and over again, reducing the eventual cost per item.

Hybrid manufacturing
