A Tunable Deep Image Processing (TDIP) model enables real-time melt pool monitoring in metal additive manufacturing, accurately isolating melt pool signatures, estimating geometries, and predicting fabrication quality at speeds of hundreds of frames per second. The novel 'hint map' tunability feature allows adaptation to various process parameters and user-defined image processing settings without extensive retraining.
Key insights
- Deep learning models can be endowed with tunability, similar to conventional image processing, by encoding control parameters as 'hint maps' in the input, addressing a common rigidity limitation.
- A multi-branch deep learning architecture can simultaneously perform complex real-time tasks like image denoising, geometric feature extraction, and material quality prediction, significantly outperforming conventional methods in speed.
- Integrating process parameters directly into a deep learning framework enables non-destructive, in-situ prediction of fabrication quality metrics, offering a leap towards autonomous AM process control.
