Abstract Scope |
The quality of parts manufactured using additive manufacturing technologies is highly dependent on the process parameters. This work explores a transfer learning based approach to estimate the relationship between the process parameters and part quality. Regression models are trained with available data for a data-rich source domain and a data-limited target domain to predict the quality of the parts in the target domain. The proposed methodology is demonstrated on polymer fused filament fabrication parts, considering ABS as the data-limited and PLA as the data-rich domain, respectively. The prediction models are used to predict the tensile strength of ABS parts as a function of print temperature, print speed, and layer height. The performance of different regression models such as random forest regression model and Gaussian process model is also investigated. |
