Quill-free additive manufacturing of fused silica glass
Quill-free additive manufacturing of fused silica glass
Additive manufacturing of high-quality macroscopic fused silica glass structures, with deposition rates of up to 1.2 mm3/s, is presented. Three co-axial nozzles were used to avoid the so-called quill effect. Homogeneous, crack-free, multilayer, as well as free-standing objects were printed using cluster-free sub-µm powders delivered to a CO2 laser-induced melt pool. Structures with an overhang of up to 45° were possible to print. Laser post-processing was used to improve the surface roughness and transparency. This system can be suitable for fabrication of advanced optical elements and devices, such as waveguides or fiber preforms.

Abstract
Additive manufacturing of high-quality macroscopic fused silica glass structures, with deposition rates of up to 1.2 mm3/s, is presented. Three co-axial nozzles were used to avoid the so-called quill effect. Homogeneous, crack-free, multilayer, as well as free-standing objects were printed using cluster-free sub-µm powders delivered to a CO2 laser-induced melt pool. Structures with an overhang of up to 45° were possible to print. Laser post-processing was used to improve the surface roughness and transparency. This system can be suitable for fabrication of advanced optical elements and devices, such as waveguides or fiber preforms.
