Chinese Researchers Revolutionize 3D Printing Speed
Imagine printing a complex, millimeter-scale object in just 0.6 seconds. That's what a team of Chinese researchers has achieved, setting a new record for 3D printing speed. This groundbreaking development could transform scientific research and industrial manufacturing.
3D printing has long been a balancing act between speed and precision. High-resolution printing of millimeter-scale objects often takes a long time, making it challenging to meet the demands of scientific research and production. But now, a team led by academician Dai Qionghai from Tsinghua University has discovered a novel approach.
The team, focusing on computational optics, found that it can capture light field information and manipulate high-dimensional holographic light fields to construct three-dimensional entities. After five years of research, they developed the digital incoherent synthesis of holographic light fields (DISH) 3D printing technology, overcoming challenges like high-speed modulation of multi-perspective light fields.
Experiments revealed that DISH technology can fabricate millimeter-scale complex structures in just 0.6 seconds, achieving a minimum printable structure size of 12 micrometers and a printing rate of up to 333 cubic millimeters per second. This technology overcomes the speed limitations of traditional point-by-point or layer-by-layer scanning methods, enabling precise projection of complex 3D light intensity distributions in an extremely short time.
Another advantage is its minimal requirement for the printing container, needing only a single optical flat surface. The container remains stationary throughout the printing process, eliminating the need for high-precision relative motion between the container and the probe, as required by traditional methods.
Dai Qionghai suggests that DISH technology could revolutionize the mass production of micro-components, such as photonic computing devices and mobile phone camera modules, and parts with sharp angles and complex curved surfaces. Its applications may expand to flexible electronics, micro-robots, and high-resolution tissue models in the future.
This breakthrough challenges the status quo and opens up exciting possibilities for the future of 3D printing. It's a testament to the power of innovation and collaboration in scientific research.
