Additives manufacturing as the word suggests is the transformative process of producing objects or systems that are stronger and lighter e.g. creation of exhaust pipes from aluminum alloys. These industries are oligopoly in nature because in manufacturing requires large economies of scale and high fixed costs. On the other hand, these industries consist of few sellers and many buyers where the sellers have control over the price of their products.

Lastly, these firms may differ in size depending on their work and scope in the market e.g. aerospace companies may be bigger.
