Abstract

Additive manufacturing and 3D printing are becoming everyday more and more strategic for the fabrication of complex materials in terms of architecture and nature. These new ways of fabricating materials are offering innovative approaches for designing material and devices hardly feasible with classical approaches at reduced cost, occupying a strategic technological position towards economic progress in developing countries. In the last ten years, most of the efforts have been devoted to metals and polymers. It is only recently that attention is given on wide band gap inorganic materials, composites and hybrids. Very few investigations have been devoted to optical materials to date and 3D printing glass is still an emerging technological area of great interest. The purpose of this project is to develop polyphosphates coacervates based ink for 3D printing of phosphate glasses, further exploring applications in photonic structures. So far, 3D printing of glasses only employed soda-lime or pure silica glasses and no approach for other compositions has been reported. Phosphate glasses are of special interest in photonics and biomedical application due to their low viscosity, low melting temperature and biocompatibility/bioactivity properties. Furthermore, 3D printing in glasses could be a powerful all purpose manufacture technique towards structured pre-forms for optical fibers, scaffolds for bioapplications and microfluidics. (AU)
