Abstract Scope |
Achieving precise geometric quality control in bio-additive manufacturing is crucial for fabricating functional tissue constructs with high fidelity. However, this can be challenging, especially when dealing with hydrogels that are difficult to 3D scan accurately. To detect any inaccuracies in the printed construct, we developed a real-time monitoring framework for extrusion-based printing processes that generates layer-by-layer nominal images of the tool path and computes the MSE/SSIM similarity score of the actual printed construct for geometrical variations. The proposed monitoring system represents a significant step towards ensuring quality control and process efficiency in bio-additive manufacturing, with implications for tissue engineering and regenerative medicine. Future research will focus on optimizing the system design and improving the accuracy of monitoring algorithms, especially in accounting for layer thickness and hydrogel material rheology, and a feedback system to correct the next layer or cancel the print given detected anomalies. |
