Abstract Scope |
Minimizing residual stresses and the resulting geometric distortion is important for enabling a wider adoption of additively manufactured parts. The toolpath during printing, including the dwell time between layers, is known to have a significant impact on the residual stress. We present a workflow that combines toolpath planning, simulation, in-situ monitoring, and optimization techniques to refine dwell control for improved geometric accuracy. This workflow integrates finite element analysis with real-time monitoring data to iteratively calibrate and validate simulation predictions, forming a feedback system that minimizes distortion. To quantify deviations, we use a structured blue light scanner to capture the geometry of printed part and compare the scanned geometry to the original CAD. This comparison allows us to assess distortion quantitatively and verify the effectiveness of optimized dwell parameters in reducing distortion. Additionally, this workflow can be adapted for convergent manufacturing processes, enhancing the accuracy and efficiency of hybrid production methods. |
