ARTICLES EN VITROCÉRAMIQUE DENSES PAR FABRICATION ADDITIVE DE FRITTE DE VERRE

摘要

A printing material and process for producing dense glass-ceramic articles by additive manufacturing are provided. The printing material includes a glass frit that densities to a degree that closely approximates the theoretical density before appreciable crystallization occurs. Densification without interference from a crystalline phase enables greater degrees of densification. Further heating of the sintered printing material induces crystallization to form glass-ceramic articles having a density approaching the theoretical density. The printing material and process enable production of high density glass-ceramic articles at modest process temperatures.
