Abstract
Devices (herein 'powder spreadability inspection tools') and methods are provided for evaluating the spreadability of powders utilized in additive manufacturing (AM) processes. In embodiments, the powder spreadability inspection tool includes a powder support surface on which a visual inspection area is provided, a spreader system including a spreader implement, and a powder dispenser. The spreader implement is movable relative to the powder support surface along a path, which extends or passes over the visual inspection area. The powder dispenser is operable to dispense a premeasured or metered volume of an AM powder sample onto the powder support surface ahead of the spreader implement. As the spreader implement moves along the path relative to the powder support surface, the spreader implement spreads a layer of the metered powder sample across the visual inspection area to allow a visual evaluation of the spreadability of the AM powder.
