Laser Powder Bed Fusion (LPBF) takes advantage of the geometric flexibility of its manufacturing method to produce highly customizable parts. This work delves into one way of functionalizing 3D printed parts by, for instance, assembling devices inside (e.g., a Sensor/Actuator System). This requires the interruption of the building process, which is enabled by the LPBF layer-wise production. The overall effects of this event are currently under study, e.g., in terms of defects generation and geometrical deviations. In particular, a method based on the use of X-ray computed tomography (CT) and specifically designed geometries inspired by previous work at University of Padova [*] is developed to investigate such effects by comparing the fabricated parts before and after the interruption.

Abstract
Laser Powder Bed Fusion (LPBF) takes advantage of the geometric flexibility of its manufacturing method to produce highly customizable parts. This work delves into one way of functionalizing 3D printed parts by, for instance, assembling devices inside (e.g., a Sensor/Actuator System). This requires the interruption of the building process, which is enabled by the LPBF layer-wise production. The overall effects of this event are currently under study, e.g., in terms of defects generation and geometrical deviations. In particular, a method based on the use of X-ray computed tomography (CT) and specifically designed geometries inspired by previous work at University of Padova [*] is developed to investigate such effects by comparing the fabricated parts before and after the interruption.Pubblicazioni consigliate
