Additive manufacturing is becoming an increasingly established production technology. However, as it is still new, the required process steps have not been uniformly defined yet. There are, for example, no industry-wide standards describing the quality control process. Among the metal powders used for additive manufacturing are different types of steel and titanium. To check the quality and purity of these raw materials, suitable processes need to be implemented. The content of various “foreign” elements, for example, should be closely monitored to ensure a high-quality end product.
