Volumetric additive manufacturing (VAM) promises a significantly improved regime of capabilities for 3D printing. Computed Axial Lithography (CAL) is a photopolymerization-based tomographic VAM process which constructs objects by projecting systematic illumination patterns into a container of photosensitive prepolymer as it rotates. This technique is used to demonstrate the manufacturing of parts that faithfully adhere to respective target geometries. A principled optimization approach is used to generate the illumination patterns by penalizing 3D dose constraint violations and is demonstrated to achieve better performance than a heuristic dose matching technique. 3D objects are experimentally fabricated using CAL, and excellent fidelity to target design is demonstrated on diverse exemplary geometries. Imperfections between design and resulting print are experimentally characterized using laser scanning measurements. Deviations below 1.05 mm are achieved (max standard deviation $=$ 0.22 mm, absolute max mean deviation $=$ 0.15 mm) on complex objects with extent of 20–40 mm that are all fabricated volumetrically in minutes.

体积增材制造 (VAM) 有望显着提高 3D 打印能力。计算机轴向光刻 (CAL) 是一种基于光聚合的断层扫描 VAM 工艺，它通过在旋转时将系统照明图案投射到光敏预聚物容器中来构建物体。该技术用于演示忠实地遵守各自目标几何形状的零件的制造。原则性优化方法用于通过惩罚 3D 剂量约束违规来生成照明模式，并被证明可以实现比启发式剂量匹配技术更好的性能。3D 对象是使用 CAL 实验制造的，并且在不同的示例几何形状上展示了对目标设计的出色保真度。设计和最终印刷品之间的缺陷使用激光扫描测量进行实验表征。偏差低于 1.05 毫米（最大标准偏差$=$ 0.22 mm，绝对最大平均偏差 $=$ 0.15 毫米）在具有 20-40 毫米范围的复杂物体上，这些物体都是在几分钟内按体积制造的。
