Accurate simulation of the printing process is essential for improving print quality, reducing waste, and optimizing the printing parameters of extrusion-based additive manufacturing. Traditional additive manufacturing simulations are very compute-intensive and are not scalable to simulate even moderately sized geometries. In this paper, we propose a general framework for creating a digital twin of the dynamic printing process by performing physics simulations with the intermediate print geometries.
- High-resolution thermal simulation of 3D printing processes
- Voxel-based geometry representation from G-code
- Adaptive octree meshes for efficient computation
- Real-time predictions faster than actual print time
- Scalable to complex geometries with sparse and dense infills
