In recent years, 3D printing has advanced rapidly. However, the technology has been trapped in a frustrating tug-of-war. If you wanted something precise, you had to wait hours. If you wanted something fast, you sacrificed the details.
But these challenges have been solved by a research team at Tsinghua University, China.
Unlike point-by-point or layer-by-layer printing, the new technique uses high-dimensional holographic light fields to create a 3D solid structure almost instantaneously.
Interestingly, it can print complex, millimeter-scale objects in just 0.6 seconds. Moreover, 3D printing maintains great detail, with feature sizes as small as 12 micrometers.
The technology offers a transformative solution for fields like biomedicine and nanotechnology by overcoming the trade-off between speed and precision.
It could pave the way for advanced applications in flexible electronics, micro-robotics, and the creation of highly detailed biological tissue models.
