打印过程实拍。 （清华团队供图） 3D打印应用广泛，但一直存在"速度和精度"的烦恼：打印材料与探头间的精密机械运动虽能保障精度，但打印效率较低，毫米级物体的高 分辨率打印往往需要几十分钟甚至几个小时才能完成，难以满足科研与生产需要。此外，现有高速3D打印对容器结构、材料粘度等也有限 制。 中国工程院院士戴琼海教授带领的清华大学成像与智能技术实验室研究团队，基于在计算光学领域深耕的实践，发现计算光学可操纵高维全 息光场构建三维实体。 团队历经5年攻关，攻克多视角光场的高速调控、拓展景深的全息图案优化算法设计等系列难题，最终创出"数字非 相干合成全息光场（DISH）"3D打印技术。 复杂结构打印产物展示。（清华团队供图） 实验表明，该技术生成毫米尺寸复杂结构的加工时间仅需0.6秒，最细可打印12微米尺寸结构，打印速率可达每秒333立方毫米。 "这是目 前已知3D打印的最高速率。"团队成员、吴嘉敏副教授说，借助创新的光学系统设计，DISH技术突破了逐点或逐层扫描模式的速度瓶颈，可 在极短时间内精准投影出复杂的三维光强分布，实现对物体的快速打印。 据新华社， 3D打印技术的性能突破关乎生物医学、微纳科技、先进制造等前 ...
