摘　　要：增材制造技术在制造复杂形状零件方面具有显着的优势,然而熔石英玻璃的3D打印技术仍有待开发。基于液晶显示3D打印成型技术,研究了脱脂、金属掺杂、烧结等工艺,并制备了致密透明的熔石英玻璃样件,研究掺杂Cr^(^(3+))、Co^(^(2+))2种金属离子的熔石英玻璃致密化和光学吸收特性。研究发现掺杂含Cr^(^(3+))、Co^(^(2+))2种金属离子的熔石英玻璃具有独特的光学吸收性能,掺杂熔石英玻璃能保持无定型结构,可对特定波段光谱进行过滤,掺杂Cr^(^(3+))的绿色熔石英玻璃对波长471nm的蓝光和波长660 nm的红光过滤明显;掺杂Co^(^(2+))的蓝色熔石英玻璃对波长597 nm的黄光和波长662 nm的红光过滤明显,在集成复杂光学元件结构应用方面拥有一定的潜力。Introduction Additive manufacturing has attracted recent attention for glass fabrication due to its advantages to manufacture parts with complex geometries.In 3D printing,various techniques such as fused deposition modeling,selective laser melting,direct ink writing,and stereolithography are developed for glass fabrication.For its high printing accuracy,fast speed,and excellent surface quality,stereolithography shows a great potential in fabricating fused quartz glass with intricate structures and optical lenses.This paper was to enhance the optical performance of fused quartz glass including optical absorption,photoluminescence and light scattering properties via infusing metal ions into the glass.We investigated the metal salt solution immersion,debinding and sintering processes based on liquid crystal display 3D printing technology.We fabricated a fused silica glass doped with Cr^(3+)and Co^(^(2+))metal ions.Methods A homogeneous solution of photopolymer was prepared via mixing 60%2-hydroxyethyl methacrylate,10%triethylene glycol diacrylate,and 30%phenoxyethanol.2,4,6-trimethylbenzoyldiphenyl phosphine oxide,Sudan orange G,and diethyl phthalate were added to the solution and dispersed for 5 min.Silica nanoparticles of 53%(in mass fraction)were then added and dispersed by a dissolver for 10 min.The photosensitive paste was cured using an LCD 3D printer.Subsequently,the printed parts were heated at 600℃for 2 h,and then soaked in a metal ions solution for 1 h.After being air-dried at 50℃for 1 h,the doped debinding part was sintered at 1280℃for 2 h.Metal ion-doped glass in the furnace can be obtained after cooling to room temperature.Results and discussion After debinding and sintering,the printed fused quartz glass parts are densified.The removal of organic binder from the debinding parts causes a contraction of the parts.The micropores disappear after the sintering process,resulting in dense parts that are colorless and transparent.Furthermore,a high concentration of the doped mental ions leads to an exten
