sequences. Sizing, surface and volume rendering can be extracted and compared with targeted dimensions. In this work, we use millimeter wave systems tomographic system (100 and 300 GHz), frequency modulated systems (100 and 300 GHz), and pulse time domain systems (100 GHz to 4 THz) for non destructive characterization of 3D printed additive manufacturing parts. The aim of this talk to to show the advantages and disadvantages of several techniques to define their application aera. This work is associated to a data processing analysis using automated segmentation, extracting of the different volumes of interest (VOI) composing the sample. A mesh is performed for each VOI to numerically calculate the dimensions, surfaces and volume which leads to 3D visualization and dimensional measurements. Overall sequence is implemented onto unique software and validated through different sample analysis.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
