| Abstract Scope |
There are several methods of finding a porous material’s permeability which refers to the ability for fluids to pass through it. The falling head test calculates permeability by measuring the time for a specified volume of liquid to flow through a sample. Alternatively, the pressure drop test passes gas through a sample and measures the pressure difference on either side of it, calculating permeability by applying Darcy’s Law. Theoretically, the permeability value calculated by both methods should be identical. Binder jetting (BJP) is a type of additive manufacturing whose created parts are naturally very porous immediately following printing and porosity can be targeted through partial sintering. Here, we will report on porous metal samples manufactured via BJP and partially sintered, apply the two previously identified permeability calculation methods, and compare the resultant values to determine those methods’ interchangeability and applicability to determine a BJP material’s permeability. |
