Additive manufacturing of borosilicate glass via stereolithography

Recent surge in additive manufacturing efforts demonstrate stereolithography as a promising technique for fabricating glass materials due to the high speed and scalability of process. However, little have been devoted manufacture borosilicate by stereolithographic One challenges is that its relatively low softening temperatures could interfere with thermal post-printing process introduce poor fidelity structure instability. Here, we report on first demonstration cerium-doped (Ce-doped) (<10%) undoped which was enabled multi-step post processing. The optical properties printed depend processing parameters (temperature, time, environment) can be readily tuned optimized wide range applications. amorphous shows good structural stability band gap 3 eV, Urbach energy 0.75 eV refractive index 2.14 8% Ce-doped glass, respectively. These results indicate fabricated suitable scintillator applications fabrication.
