WebMar 10, 2024 · Wednesday - March 10, 2024. Porosity is often thought to be a major concern in metal additive manufacturing, but current levels of porosity are not like they were fifteen years ago. Most additive parts we typically see today are at least 99.5% dense, and in many cases, 0.5% porosity does not have an influence on the properties of the part. WebHowever, Balthazard et al., through their investigation into the porosity of RBCs, concluded, that the less viscous the material was, the greater its porosity, regardless of the handling conditions . Highly viscous RBCs need a higher condensing force to adapt the material to the walls, which may squeeze out the air bubbles from the material [ 39 ].

Porosity is a fraction between 0 and 1, typically ranging from less than 0.005 for solid granite to more than 0.5 for peat and clay. The porosity of a rock, or sedimentary layer, is an important consideration when attempting to evaluate the potential volume of water or hydrocarbons it may contain. See more Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%.
