In ‘Applying Neural-Network-Based Machine Learning to Additive Manufacturing: Current Applications, Challenges, and Future Perspectives,’ authors Xinbo Qi, Guofeng Chen, Yong Li, Xuan Cheng, and Changpeng Li investigate how machine learning (ML) and neural network algorithms (NN) can be applied to additive manufacturing.
While the many benefits of AM processes continue to be uncovered, availing themselves to countless industries today, there are still numerous drawbacks and scenarios for defects which continue to challenge users around the world—from porosity to anisotropic microstructures, to distortion, and more.Prototypes may not always require perfection as simple models, however, parts meant for true functional, industrial use must be strong and produced without threat to their overall integrity. The authors point out the importance of understanding the following:
- Powder’s metallurgical parameters
- 3D printing process
- Mechanical properties of AM parts
In machine learning, the NN algorithm is only increasing in popularity for use and is currently under ‘rapid development,’ most often employed in computer vision, voice recognition, language processing, and self-driving vehicles. It is a supervised type of ML, operating with labeled data, and within additive manufacturing is showing good suitability for ‘agile manufacturing’ in industry.
“The NN has exerted a deep and wide impact on all value chain innovation in industry—from product design, manufacturing, and qualification to delivery—and it is believed that the impact of NN will be increasingly intensive,” state the researchers.
The most common types of NNs are:
- Multilayer perceptron (MLP)
- Convolutional neural network (CNN)
- Recurrent neural network (RNN)
Sensors have been created for the hardware and software, and a variety of different sensors can be used for in situ measurements too.
“The scope of this work covers many variants of NNs in various application scenarios, including: a traditional MLP for linking the AM process, properties, and performance; a convolutional NN for AM melt pool recognition; LSTM for reproducing finite-element simulation results; and the variational autoencoder for data augmentation. However, as they say, ‘every coin has two sides.’
“It is difficult to control the quality of AM parts, while NNs rely strongly on data collection. Thus, some challenges remain in this interdisciplinary area. We have proposed potential corresponding solutions to these challenges and outlined our thoughts on future trends in this field,” concluded the researchers.
