Gas pycnometry can be used to assess the skeletal density of solids like 3D printed parts and their associated raw materials. Assessing the skeletal density (and in cases of parts of regular shape, comparing to bulk density) and the open cell content of 3D printing materials such as metals, ceramics, and polymers allows for differences in printed materials to readily be determined. These differences are often influenced by user-selected printer parameters, and can affect the final part’s properties and suitability for its intended application.
