Tsinghua University Develops Holographic Light Field 3D Printing Tech
Researchers at Tsinghua University have created a new 3D printing technology called DISH, capable of fabricating millimeter-scale objects in just 0.6 seconds.
A team at Tsinghua University has announced the development of a novel 3D printing technology named DISH (Digital Light Field Printing). This innovative method utilizes holographic light fields to rapidly solidify photopolymer resins, enabling the creation of millimeter-sized objects with remarkable speed.
The DISH system achieves its rapid fabrication rate by projecting a sequence of holographic images. These images are designed to precisely control the light intensity and direction at each point within the resin vat, thereby initiating polymerization only in the desired areas. This volumetric curing approach bypasses the layer-by-layer limitations of traditional 3D printing methods.
During the printing process, the DISH technology can simultaneously cure multiple points within the resin, significantly accelerating the overall build time. The researchers demonstrated the system's capability by successfully printing millimeter-scale solid objects in a mere 0.6 seconds, a substantial improvement over existing technologies for comparable object sizes and complexity.
This advancement in speed and volumetric curing opens new possibilities for rapid prototyping and the manufacturing of small, intricate components. The ability to print complex shapes quickly and efficiently could have implications across various industries, from micro-optics to biomedical devices.
The development of DISH by Tsinghua University represents a significant leap in volumetric additive manufacturing. By employing holographic light fields for simultaneous, multi-point curing, it dramatically reduces print times for millimeter-scale objects. This rapid fabrication capability is crucial for applications requiring quick iteration and on-demand production of small, complex parts, aligning with the broader industry push for faster and more efficient additive manufacturing processes.
