Using additive manufacturing for making cemented carbide components means far greater design flexibility compared to producing components by, for example, press and sintering methods. With additive manufacturing, virtually any component geometry is possible.

Application areas
Cemented carbide is characterized by high durability and wear resistance. Therefore, components made from cemented carbide have a typically 3-20 times longer service life compared to steels and other alloys. This makes cemented carbide suitable for a range of applications, such as wear parts.
