体积增材制造是一种新型的制造方法，允许快速，自由，无层的3D打印。类似于计算机断层扫描（CT），该方法将动态光图案投射到光敏树脂的旋转缸中。这些光图案在光敏树脂内建立三维能量剂量，在几秒钟内固化所需物体的体积。与立体光刻或数字光打印等已建立的顺序制造方法不同，体积增材制造为可用于打印的材料提供了新的机会。这些包括粘性丙烯酸酯和弹性体、环氧树脂（和具有空间控制刚度的正交环氧-丙烯酸酯制剂）制剂、可调刚度硫醇-烯和形状记忆泡沫、聚合物衍生的陶瓷、基于二氧化硅-纳米复合材料的玻璃和用于载有细胞的生物织物的基于明胶的水凝胶。在这里，我们回顾了这些材料，强调了使它们适应体积增材制造的挑战，并讨论了它们所呈现的前景。在线版本包含补充材料，可通过10.1557/s43579-023-00447-x获取。
Volumetric additive manufacturing is a novel fabrication method allowing rapid, freeform, layer-less 3D printing. Analogous to computer tomography (CT), the method projects dynamic light patterns into a rotating vat of photosensitive resin. These light patterns build up a three-dimensional energy dose within the photosensitive resin, solidifying the volume of the desired object within seconds. Departing from established sequential fabrication methods like stereolithography or digital light printing, volumetric additive manufacturing offers new opportunities for the materials that can be used for printing. These include viscous acrylates and elastomers, epoxies (and orthogonal epoxy-acrylate formulations with spatially controlled stiffness) formulations, tunable stiffness thiol-enes and shape memory foams, polymer derived ceramics, silica-nanocomposite based glass, and gelatin-based hydrogels for cell-laden biofabrication. Here we review these materials, highlight the challenges to adapt them to volumetric additive manufacturing, and discuss the perspectives they present.
