ABSTRACT
Micro/nanorobots have attracted much attention because of their potential to perform complex tasks with high precision under controlled actuation within the human body, such as targeted cargo delivery, lesion exploration, and minimally invasive surgery. Among the various emerging fabrication technologies, multidimensional additive manufacturing (MAM) technology can enable the design and fabrication of complex structures with multifunctional characteristics. Compared with traditional manufacturing methods, MAM significantly reduces production complexity and time while enhancing design flexibility and customization. This review provides a comprehensive overview of MAM technologies for constructing micro/nanorobots, along with their applications and associated challenges in the biomedical field. In addition, emerging MAM approaches, including 4D, 5D, and 6D printing assisted by physical intelligence, machine learning, and artificial intelligence show great potential for designing and fabricating more sophisticated and intelligent micro/nanorobots, thereby advancing their clinical translation in the near future.
