Chinese scientists have achieved a groundbreaking leap in additive manufacturing, successfully employing micro-nano 3D printing technology to fabricate intricate items. This advancement heralds a new era in precision and capabilities of 3D printing, enabling the production of highly detailed and complex structures at microscopic scales.
Revolutionizing Electronics, Biomedicine and Materials Science
This cutting-edge technology is set to revolutionize the landscape of electronics, biomedicine, and materials science. It allows for the manufacturing of intricate structures and has potential applications in organ-on-a-chip research and the development of flexible thermoelectric devices for power generation and refrigeration. The researchers have demonstrated the technology by manufacturing items such as a dragon, the Bird’s Nest (China’s National Stadium), the Red Boat, and the Yellow Crane Tower, highlighting the high precision of the printing process.
Micro-Nano 3D Printing: A Leapfrog in Additive Manufacturing
The emerging subject of nano science and technology is highly valued in China, and the development of micro-nano 3D printing technology is expected to propel further innovation and research, promising a leapfrog advancement in the future. By manipulating materials at the nano-scale, scientists can create objects with unprecedented accuracy and complexity, expanding the horizons for additive manufacturing.
Building Human Organs on a Chip with Micro-Nano Robots
Scientists from Shanghai Jiao Tong University have developed a multi-stage delivery strategy of magnetically controlled micro-nano robots based on a human organs on a chip (OOC) model they built. With the aid of micro-nano 3D printing technology, they constructed a hierarchical vascularized OOC model that can recapitulate the structure and function of different organs in the human body. The team can infuse magnetically guided micro-nano robots into these OOCs and navigate them inside blood vessels with an external magnetic field. The applications of these vitro models include facilitating drug screening, reducing the cost of drug research, and enhancing the efficiency of drug development. They could also be used in medical treatment, for example, building a vitro OOC for a tumor patient as a substitute for the patient to try different drugs and guide clinical medication.
