我科学家革新3D打印关键技术

Core Viewpoint - The article discusses the breakthrough in 3D printing technology through the development of "Digital Holographic Field" (DISH) technology by Tsinghua University's team, which significantly enhances both speed and precision in 3D printing, addressing the existing limitations in traditional methods [1][2]. Group 1: Technology Advancements - DISH technology improves the exposure speed of traditional volumetric 3D printing by several times, achieving a record exposure time of 0.6 seconds for complex structures at the millimeter scale, compared to the 30 seconds typical of traditional methods [2][3]. - The technology allows for the use of a wide range of materials, from low-viscosity solutions to high-viscosity resins, due to its short exposure time that minimizes the effects of material flow [2][3]. Group 2: Applications and Implications - DISH technology is expected to revolutionize various fields, including biomedical applications where it can print vascular models and in situ structures using biocompatible materials, thus opening new avenues for tissue engineering and high-throughput drug screening [3]. - In engineering manufacturing, DISH technology could be integrated into production lines for mass production of photonic devices and complex components, enabling the printing of parts with sharp angles and intricate surfaces [3].
