摘要: 投影式3D打印是一种基于光聚合原理的增材制造技术,通过利用空间光调制器生成动态掩膜,并将位图图像投射到光敏材料表面,以实现固化成形。投影技术可分为面投影和体投影两类,在众多3D打印技术中,面投影技术具有最高的分辨率/制造时间比,而体投影技术则具有远超传统打印技术的打印速度,因而投影式3D打印被视为极具潜力的技术路线。然而,当该技术应用于生物3D打印领域,即采用含细胞的生物墨水时,其可打印性、分辨率以及墨水要求会发生显著变化,进而带来诸多挑战。本综述系统总结了投影式生物3D打印的技术原理与关键挑战,分析了近年来的新技术与新应用,并结合生物医学的应用需求,总结了切实可行的优化策略,旨在为该领域的研究与发展提供有价值的参考。

Abstract: Projection-based 3D printing is an additive manufacturing technology grounded in the principle of photopolymerization. It employs a spatial light modulator to generate a dynamic mask and projects a bitmap image onto the surface of photosensitive materials to achieve curing and forming. Projection techniques can be categorized into two types: surface projection and volumetric projection. Among the various 3D printing technologies, surface projection offers the highest resolution/time to manufacturing ratio, while volumetric projection boasts printing speeds that far surpass those of traditional printing methods. Consequently, projection-enabled 3D printing is regarded as a highly promising technological approach. However, when applied to bioprinting—specifically with the use of cell-laden bioinks—its printability, resolution, and ink requirements undergo significant changes, presenting a range of challenges. This review systematically summarizes technical principles and primary challenges of projection-enabled 3D bioprinting, analyzes recent advancements in techniques and applications, and proposes practical optimization strategies tailored to the demands of biomedical applications. It aims to provide valuable insights and references for research and development in this field.
