Abstract (en)
[origin: WO2020229834A1] A method and apparatus for analysing a metal powder for use in an additive manufacturing process involving: providing the powder in a close packed state adjacent a barrier; illuminating a region of the powder through the barrier; separately detecting the illuminating radiation received back from different parts of the illuminated region of the powder through the barrier, to produce an output which depends on the detected radiation; and processing the output to determine one or more properties of the powder. The barrier may be a wall of a container or conduit. The apparatus may form part of powder transport or additive manufacturing apparatus.
