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.

Claim (Index 18):
A method for evaluating a spreadability of an additive manufacturing (AM) powder, the method carried-out utilizing a powder spreadability inspection tool including a spreader implement and a powder support surface having a visual inspection area, the method comprising:\n dispensing a predetermined amount of an AM powder sample onto the powder support surface; utilizing the spreader implement to spread the AM powder sample across the visual inspection area, the AM powder sample spread in a powder layer having a substantially uniform thickness; and visually assessing the spreadability of the AM powder sample based, at least in part, on coverage of the visual inspection area by the powder layer.
