  1. This paper presents hyperparameter tuning techniques for a deep learning predictive model with applications in additive manufacturing processes. Bioprinting is an additive manufacturing process which utilizes biomaterials, cells, and growth factors to build functional tissue constructs for biomedical applications. In this research, we evaluate the hyperparameter space using grid search technique to tune the perceptron deep learning hyperparameters for optimal prediction of additive manufacturing outcomes. Hyperparameter entities include number of neurons, learning rate, and number of epochs to run machine learning models. Five input parameters and three output variables were evaluated for a typical additive manufacturing process. A comparative analysis is conducted to demonstrate improved runtime and lower root mean squared error for additive manufacturing predictive models. The results from this research are extensible to several additive manufacturing processes including 3D bioprinting.
