Latest techniques in Spreadability Testing and Layer Quality Control
Experts at the Wolfson Centre for Bulk Solids Handling Technology have designed an instrument to quantify the behaviour of a powder when spreading for Additive Manufacturing.
This incorporates a shadowgraphy technique (shown below), used to quantify powder bed surface roughness.
