In the rapidly evolving world of micro/nano device fabrication, a groundbreaking approach is emerging that could revolutionize industries, including energy. Researchers, led by Bin Wang from the Jiangsu Key Laboratory for Design and Manufacturing of Precision Medicine Equipment at Southeast University in China, have published a comprehensive review in the *International Journal of Extreme Manufacturing* (which translates to *International Journal of Extreme Manufacturing* in English). This review explores the potential of field-assisted additive manufacturing (FAM), a cutting-edge method that combines traditional additive manufacturing with external fields like magnetic, acoustic, or electric fields to enhance precision and functionality.
Additive manufacturing, commonly known as 3D printing, has long been praised for its flexibility and ability to create complex structures. However, when it comes to micro/nano devices, traditional methods fall short in achieving the necessary precision and material integration. “The challenges in material alignment control, microstructural organization, and multifunctional integration have limited the potential of additive manufacturing in this realm,” explains Wang. FAM addresses these limitations by using external fields to regulate material alignment and structural organization, leading to improved precision and enhanced material properties.
The review delves into the mechanisms and processes of FAM, highlighting its applications in various sectors, including microrobotics, biomedical devices, and electronic sensors. For the energy sector, the implications are significant. Micro/nano devices fabricated using FAM could lead to more efficient energy storage solutions, advanced sensors for monitoring energy systems, and innovative materials for renewable energy technologies. “The ability to integrate multiple materials and achieve complex 3D architectures opens up new possibilities for energy applications,” says Wang.
FAM’s potential extends beyond the energy sector. In healthcare, for instance, the precise fabrication of micro/nano devices could lead to advanced drug delivery systems and highly sensitive diagnostic tools. The review also provides a comparative overview of different FAM approaches, highlighting their unique advantages and typical applications.
Despite its promise, FAM faces several challenges. The review comprehensively assesses these hurdles, including the need for advances in spatial precision control, intelligent process integration, and multi-field coupling optimization. Addressing these challenges will be crucial for the widespread adoption of FAM in various industries.
As researchers continue to explore the capabilities of FAM, the future of micro/nano device fabrication looks increasingly promising. The review by Wang and his team serves as a foundational theoretical framework, guiding researchers and industry professionals in harnessing the potential of FAM for high-performance micro/nano device fabrication. With further advancements, FAM could pave the way for innovative solutions in energy, healthcare, and beyond, shaping the future of technology and manufacturing.
