Lipcon: A Physics-Aware Spatially Resolved Light Penetration Compensation Method for Low-Cost 3D-Printed Microfluidics
DescriptionThree-dimensional (3D) printing enables low-cost, rapid prototyping of complex microfluidic biochips, but light penetration during printing distorts small, multi-layered structures. Existing solutions are either inaccessible or overlook localized geometric effects, leading to inaccuracies that degrade device performance. We propose a novel physics-aware, data-driven design-for-manufacturing approach to improve dimensional fidelity. Using a new dataset of design-fabrication discrepancies, our machine learning-assisted method predicts spatially resolved compensation values. Experiments on complex multi-layer devices demonstrate that our method significantly enhances geometric accuracy and consistently outperforms existing compensation strategies, even with low-cost hobby-grade printers and off-the-shelf resins.
