Abstract Scope |
Direct ink write (DIW) additive manufacturing (AM) has enabled an elegant fabrication pathway for a vast material library. Nonetheless, each material requires optimization of printing parameters generally determined through significant trial-and-error testing. To eliminate arduous, iteration-based optimization approaches, we use machine learning (ML) algorithms such as neural networks (NNs) which provide opportunities for automated process optimization. In this talk, we highlight the use of computer vision (CV) measurements of DIW print parameters for NN training. By using trained NNs as surrogate models for the DIW process, inverse optimization problems could be solved and implemented in less than a second for real-time print optimization. The methods developed and presented in this talk eliminate user-intensive, time-consuming, and iterative parameter discovery approaches that currently limit accelerated implementation of AM processes. The approaches outlined in this talk can be generalized to provide real-time monitoring and optimization pathways for increasingly complex AM environments. |
