Patent number: 11680017Abstract: A geopolymeric ink formulation for direct 3D printing containing a geopolymeric formulation whose components are present in such proportions as to be subjected to a geopolymerization reaction and to provide, at the end of the reaction, a solid geopolymer and wherein the formulation, before and during at least a part of the geopolymerization reaction, wherein three-dimensional chemical bonds have not yet been formed, forms a reversible-gel, non-Newtonian, viscoelastic fluid. The formulation is extruded through a 3D printing tool equipped with nozzle into strands according to a geometry such as to create a three-dimensional structure on one or more layers. The extrusion preferably takes place within a hydrophobic liquid, such as oil.Type: GrantFiled: August 2, 2021Date of Patent: June 20, 2023Assignee: ITT Italia S.R.L.Inventors: Paolo Colombo, Giorgia Franchin, Hamada Said Abdelwahab Elsayed, Agustin Sin Xicola

Publication number: 20220324741Abstract: A method for producing a solid body of glass is described. The method comprises providing a polymerisable composition, curing the polymerisable composition to obtain a cured body, subjecting the cured body to thermal debinding to substantially remove the organic components in the cured body, and subjecting the cured body to sintering to obtain a solid body of silica glass. The polymerisable composition one or more at least partially organic polymerisable compound(s) which form a liquid composition at operating temperature and a solid source of silica as colloidal silica particles or silica glass micro-/nanoparticles dispersed in the liquid composition. The one or more at least partially organic polymerisable compounds comprises at least one organosilicon compound as a second source of silica that is liquid or solubilisable in the liquid composition at operating temperature to thereby increase the silica loading of the cured body prior to sintering.Type: ApplicationFiled: June 5, 2020Publication date: October 13, 2022Inventors: Paolo Colombo, Giorgia Franchin, Giulio Giometti, Johanna Schmidt, Anna De Marzi

Patent number: 10266442Abstract: In illustrative implementations of this invention, a crucible kiln heats glass such that the glass becomes or remains molten. A nozzle extrudes the molten glass while one or more actuators actuate movements of the nozzle, a build platform or both. A computer controls these movements such that the extruded molten glass is selectively deposited to form a 3D glass object. The selective deposition of molten glass occurs inside an annealing kiln. The annealing kiln anneals the glass after it is extruded. In some cases, the actuators actuate the crucible kiln and nozzle to move in horizontal x, y directions and actuate the build platform to move in a z-direction. In some cases, fluid flows through a cavity or tubes adjacent to the nozzle tip, in order to cool the nozzle tip and thereby reduce the amount of glass that sticks to the nozzle tip.Type: GrantFiled: January 23, 2018Date of Patent: April 23, 2019Assignee: Massachusetts Institute of TechnologyInventors: John Klein, Giorgia Franchin, Michael Stern, Markus Kayser, Chikara Inamura, Shreya Dave, Neri Oxman, Peter Houk
