Manufacturing of complex metal parts by additive manufacturing is becoming more widespread as it offers greater design flexibility and reduced waste compared with traditional manufacturing processes. For powder based processes the quality of the raw metal powder is process critical in terms of the packing behaviour and flow characteristics of the powder. This can influence manufacturing efficiency and both the integrity and quality of the finished part.

In this webinar we will show why powder characteristics are so critical for additive manufacturing and how these characteristics can be measured and controlled to achieve optimum packing and processability.
