| Abstract Scope |
Understanding uncertainty in additive manufacturing is critical to advancing precision and reliability in 3D printing. This study quantifies structural deviations in fabricated honeycomb topologies using an in-house 3D printer under varying process parameters. Deviations from intended CAD geometries are analyzed to assess inherent process-induced imperfections. Multiple batches are fabricated, each using different printing parameters, to evaluate uncertainty as a function of these variables. A novel image-based uncertainty quantification (UQ) approach is employed: 2D images of the printed samples are compared to both the original CAD models and to other samples within the same batch. This enables assessment of both absolute geometric fidelity and batch-to-batch consistency. The findings support broader efforts in UQ for additive manufacturing and contribute to developing more robust fabrication methodologies that improve part quality and repeatability. |
