Weband the build orientation (2 levels) for a constant scan speed of 600 mm/s. The tensile specimens were scanned using a micro-CT system before and after tensile testing. The porosity of the specimens varied significantly a ccording to the energy density and the build direction, but only a minor effect of the location change was observed. The ... WebJun 13, 2024 · Du Plessis et al. noted that a past downside of using micro-CT in porosity studies was that it usually required time-consuming scans and custom software, but current laboratory-based micro-CT scanners have relatively fast scan times with immediate image reconstruction. Powerful and comprehensive 3D image analysis packages now exist for ...
