A parameter-aware graph neural network for estimation of manufacturing resources in additive manufacturing

Additive Manufacturing (AM) offers unprecedented design freedom, yet evaluating the manufacturing resources required for complex geometries remains a significant computational bottleneck during the early design phase. Traditional slicing software, while accurate, is too slow to support high-frequency iterative workflows such as Generative Design. To address this, we propose the Parameter-Aware Geometric Estimator (PAGE-Net), a Graph Neural Network (GNN) framework designed to instantly predict Life Cycle Inventory (LCI) data–specifically Part Mass, Support Mass, and Total Print Time–directly from raw 3D meshes. Unlike existing voxel-based deep learning methods that suffer from discretization errors or static parameter assumptions, PAGE-Net leverages Feature-Steered Graph Convolutions (FeaStConv) to extract topological features from the native mesh while dynamically incorporating user-defined printing parameters (e. g. , infill density, layer height). Trained and validated on a comprehensive dataset of approximately 90, 000 geometries using a robust 3-fold cross-validation scheme, the model achieves high predictive accuracy, with R² scores exceeding 0. 96 for material and time estimation. Computational benchmarks demonstrate an average inference time of 77 milliseconds per object–offering a speedup of approximately 30 compared to optimized command-line slicing. By providing near real-time feedback on manufacturing resources, this framework serves as a critical enabler for data-driven Eco-Design and automated topology optimization.
