Manufactured goods are necessary for trade. According to the World Trade Organization, 80% of interregional trade is in goods, and only 20% is in services. For the U.S., the statistics are about the same. Manufacturing, therefore, plays an important part in the functioning of a nation’s economy. Despite these statistics, manufacturing is considered to be a stagnant industry. It is often said that unlike the software industry, manufacturing has not kept pace with the changing times. However, a promising new technology is about to change our fundamental notions about manufacturing.
Additive manufacturing is a transformative approach to production of goods that enables the creation of lighter, stronger systems and components. Additive manufacturing (AM) uses CAD software or 3D scanners to direct hardware to deposit material, layer upon layer, in precise shapes and patterns. As its name implies, additive manufacturing adds material to create an object. By contrast, when you create an object by traditional means, it is often necessary to remove material through milling, machining, carving, shaping or other means.
Due to its ability to allow high degrees of flexibility in product design and manufacturing, AM can be used to produce extremely complex structures, which is usually not possible through traditional techniques. With the potential to significantly reduce material waste, and the amount of production steps, additive manufacturing is poised to transform the manufacturing vertical provided it is implemented properly.
