3D printing technology has been at the forefront of revolutionizing manufacturing processes, allowing for the creation of custom parts with intricate designs. However, ensuring the strength and durability of 3D-printed metal parts remains a challenge. At Arizona State University, researchers from the School of Computing and Augmented Intelligence are leveraging artificial intelligence to enhance the metal 3D printing process, particularly with stainless steel.
Professors Aviral Shrivastava and Ashif Iquebal have embarked on a project funded by the National Science Foundation to advance additive manufacturing. Their goal is to predict and control the formation of metals during the 3D printing process. The team aims to print a complex naval propeller using 316L stainless steel, a project that demands precision to engineer the metal’s properties at a microscopic level.
The internal structure of a material, known as the microstructure, plays a crucial role in its performance characteristics. Variations in factors like cooling rates during printing can significantly impact the material’s properties. By integrating AI with physics principles, the researchers are developing a system that can predict how a metal’s internal structure will evolve during the printing process.
The team’s innovative approach involves training AI to learn and apply physics concepts efficiently, reducing the need for extensive data and complex calculations. This AI-powered system aims to streamline simulations and optimize printing parameters, ultimately enhancing the quality and predictability of 3D-printed metal components.
Industrial applications are a key focus of the research, with a particular emphasis on sectors like aerospace, defense, and energy where precision and reliability are paramount. By providing manufacturers with tools to accurately predict and control material properties, the project aims to usher in a new era of precision manufacturing and minimize costly trial-and-error processes.
The researchers are utilizing state-of-the-art 3D printing technology, including a high-tech printer with a six-axis robotic arm and lasers, to create a large naval propeller. By comparing the predicted microstructure with the actual results, the team seeks to validate the accuracy and effectiveness of their AI-powered system. The project’s outcomes are expected to enable manufacturers to fine-tune 3D printing processes efficiently and achieve desired material properties with fewer iterations.
Furthermore, the research team plans to make their software and tools accessible to a wider audience, facilitating faster simulations and advancements in various fields. The integration of AI and materials science exemplifies the intersection of industrial engineering and computer science, highlighting the potential for transformative innovations in advanced manufacturing.
Through their collaborative efforts, the ASU researchers are pioneering a new frontier in additive manufacturing, setting the stage for enhanced precision, efficiency, and reliability in metal 3D printing. By bridging the gap between research and industry needs, they are spearheading advancements that have far-reaching implications for the future of engineering and manufacturing.
