Abstract
We describe a simple device called Standard Spreadability Tester (SST). The idea behind the SST is that instead of trying to predict how a powder will spread using the powder's intrinsic properties (e.g., PSD, morphology, surface, and chemical makeup) or how it performs under some other stress conditions, we subject the powder directly to a conditions of stress very similar to what it sees in a Powder Bed Fusion (PBF) machine. In brief, the SST provides a test method that is straightforward and can be run in laboratory or commercial setting. In this work, we have described the design of the device and proved the concept by preliminary testing. The remaining potential improvements have been also discussed.
