| Abstract Scope |
Binder jetting process monitoring largely depends on simple optical sensing methods. These methods lack the ability of capturing mechanical roller-powder interactions. This study presents a novel in-situ monitoring approach which transforms the roller into a diagnostic probe by measuring roller displacement during powder spreading with micron resolution. Process parameters such as layer thickness, ambient humidity, roller speed, and saturation produce unique displacement signals. These changes can be monitored to gain insights into the process variable relationships. In this work, the displacement response is used to identify the thresholds at which spreading behavior is no longer influenced by underlying powder layers. The relationship between roller displacement and packing fraction of green parts is measured. The results are used to evaluate the impact of bound powder on the density of subsequent spread layers. |
