This study proposes an intelligent approach combining transfer learning and gradient-boosting decision trees to investigate the effects of FDM printing parameters on surface quality. Experimental results validate the effectiveness of this approach and provide valuable insights.
3D printing has the potential to revolutionize industrial manufacturing through efficient and sustainable techniques. Fused Deposition Modeling (FDM) is a broadly deployed technique among various 3D printing methods. However, the surface quality of FDM is greatly influenced by multiple factors, making it challenging to unravel the relationship between printing quality and parameter settings. To break through this bottleneck, this study proposes an intelligent approach that combines Transfer Learning (TL)-based Feature Extractor (FE) and Gradient-Boosting Decision Trees (GBDT) to investigate the effects of FDM printing parameters on surface quality. Experiments are conducted in the laboratory to validate the effectiveness of the FE-GBDT, which is then compared with the exemplary Machine Learning (ML) algorithms. The results show that our proposed TL model can achieve high precision and accuracy over 0.9900, demonstrating the efficacy of FE-GBDT in deciphering the impact of FDM printing parameters on surface quality. The contribution of each parameter is evaluated and indicates that layer height could dramatically affect the surface quality with an importance score of 0.626. The results provide valuable insights for the 3D printing community, proving that the FE-GBDT approach offers improved generalization, faster training, enhanced feature extraction, addressing data scarcity, and the ability to leverage the strengths of both approaches for superior performance across various tasks.
