Scalable, massive fabrication of complex three-dimensional (3D) structured highly transparent Nd: YAG (Y₃Al₅O₁₂) ceramics was achieved by a lithography-based (photopolymerization) digital light processing or digital light projection (DLP) 3D printing method. 3D-printed ceramic green bodies with a printing layer height of 25 µm and an xy resolution of 40 µm were fabricated by using a photocurable slurry with 39 vol% solid loading. The developed slurry exhibited a stable high viscosity of 80–340 Pa s over a large shear rate range. A specially designed pre-sintering treatment based on YAM (Y₄Al₂O₉) phase formation was applied to prevent cracking and bubbling formation in the DLP 3D printing approach for fabricating highly transparent Nd: YAG ceramics. This thermal treatment also reduced the average grain size, leading to a higher optical quality. Following a series of thermal treatments, the sintered transparent ceramics reached a relative density of 99.9% with a maximum in-line transmittance of 80% in the visible wavelength range. Moreover, the fabricated Nd-doped YAG exhibited 1064-nm emission under 808-nm laser excitation.

通过基于光刻的（光聚合）数字光处理或数字光投影 (DLP) 3D 打印方法实现了复杂三维 (3D) 结构高透明 Nd:YAG (Y ₃ Al ₅ O ₁₂ ) 陶瓷的可扩展、大规模制造. 3D 打印陶瓷生坯的打印层高度为 25 µm，xy 分辨率为 40 µm，通过使用固含量为 39 vol% 的光固化浆料制造。开发的浆料在大剪切速率范围内表现出 80-340 Pa s 的稳定高粘度。基于 YAM (Y ₄ Al ₂ O ₉) 相形成用于防止在 DLP 3D 打印方法中形成裂纹和起泡，以制造高度透明的 Nd:YAG 陶瓷。这种热处理还降低了平均晶粒尺寸，从而提高了光学质量。经过一系列热处理，烧结后的透明陶瓷的相对密度达到 99.9%，在可见光波长范围内的最大在线透射率为 80%。此外，制造的 Nd 掺杂 YAG 在 808 nm 激光激发下表现出 1064 nm 发射。
