Development of functionalized phosphate materials for extrusion-based 3D-printing
Résumé
3D-printing of inorganic vitreous materials has seen a growing interest worldwide for multiple applications. Phosphate glasses are known for their high solubility for rare earth and metallic ions, good chemical stability and good thermal properties making them compatible with processing at moderate temperature (<500°C). Here, phosphate glass compositions and thermal properties were adapted and optimized for extrusion-based 3D-printing via Fused Deposition Modeling. Both aluminum phosphate glass compositions and novel transparent zinc hydrated phosphate materials were investigated. The structure and properties of the synthetized materials were studied using vibrational and solid-state NMR spectroscopies. The 3D-printed materials were characterized by SEM, vibrational and luminescence spectroscopy. The residual porosity was quantified by X-ray tomography. These glass matrices offer new opportunities for 3D-printing of inorganic vitreous materials and composites.
