Title (EN) DENSE GLASS-CERAMIC ARTICLES VIA ADDITIVE MANUFACTURE OF GLASS FRIT
(FR) ARTICLES EN VITROCÉRAMIQUE DENSES PAR FABRICATION ADDITIVE DE FRITTE DE VERRE
Abstract:
(EN) 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.
(FR) L'invention concerne un matériau d'impression et un procédé de production d'articles en vitrocéramique denses par fabrication additive. Le matériau d'impression comprend une fritte de verre qui se densifie à un degré qui s'approche étroitement de la densité théorique avant qu'une cristallisation appréciable ne se produise. Une densification sans interférence à partir d'une phase cristalline permet d'obtenir des degrés de densification supérieurs. Un chauffage supplémentaire du matériau d'impression fritté induit une cristallisation pour former des articles en vitrocéramique ayant une densité s'approchant de la densité théorique. Le matériau d'impression et le procédé permettent la production d'articles en vitrocéramique à haute densité à des températures de traitement modestes.
