| Abstract Scope |
Additive Manufacturing’s layer-wise construction is susceptible to intrinsic process variation and fabrication errors. In-situ monitoring techniques have been proposed to detect errors, but limit inspection to a localized deposition or final part state, failing to capture how formed layers change throughout processing. Embedded 3D scanning can address these limitations, yet conducting layer-wise evaluation of high-resolution scans presents significant data management and optical challenges for compatibility with a production environment. We present a novel methodology to rapidly capture and characterize error using a digitally integrated Structured Light Scanning system and Signed Distance Function approach. Using this approach, in-situ deviation of printed structures can be analyzed within seconds over relatively large areas (250 cm2) at a high spatial resolution (0.3mm), which affords real-time correction of subtractive and additive toolpaths. While the proposed method is process agnostic, it is validated in this work via a layer-by-layer analysis of hybrid Wire-Arc AM (WAAM) processing. |
