Publication number: 20240110070Abstract: A photoresin formulation for volumetric additive manufacturing contains a photo-curable mixture of: a monomer (e.g., an acrylate-based monomer); a photoinitiator; a polymerization inhibitor (e.g., molecular oxygen (O2)); and, a reducing agent reactive with a free radical species (e.g., a peroxyl radical) formed from the polymerization inhibitor. The reducing agent permits faster printing of objects from the photoresin formulation in a volumetric additive manufacturing process to produce 3D objects of high fidelity.Type: ApplicationFiled: January 30, 2023Publication date: April 4, 2024Inventors: Yujie ZHANG, Antony ORTH, Daniel WEBBER, Kathleen SAMPSON, Thomas LACELLE, Chantal PAQUET, Hendrick de HAAN

Publication number: 20230357566Abstract: Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a polymer matrix comprising a first polymer material and a second polymer material that are immiscible with each other, and a plurality of piezoelectric particles located in at least a portion of the polymer matrix. The piezoelectric particles may remain substantially non-agglomerated when combined with the polymer matrix. The compositions may define an extrudable material that is a composite having a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste. Additive manufacturing processes using the compositions may comprise forming a printed part by depositing the compositions layer-by-layer.Type: ApplicationFiled: March 22, 2022Publication date: November 9, 2023Applicants: XEROX CORPORATION, NATIONAL RESEARCH COUNCIL OF CANADAInventors: Sarah J.

PIEZOELECTRIC COMPOSITES CONTAINING A SACRIFICIAL MATERIAL AND USE THEREOF IN ADDITIVE MANUFACTURING
Publication number: 20230122929Abstract: Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles located in a polymer matrix comprising a first polymer material and a sacrificial material that are immiscible with each other. The sacrificial material, which may comprise a second polymer material, may be removable from the first polymer material under specified conditions. The piezoelectric particles may remain substantially non-agglomerated when combined with the polymer matrix. The polymer matrix may be treated to remove the sacrificial material to introduce a plurality of pores. The compositions may have a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste.Type: ApplicationFiled: March 22, 2022Publication date: April 20, 2023Applicants: XEROX CORPORATION, NATIONAL RESEARCH COUNCIL OF CANADAInventors: Sarah J.

Patent number: 10954406Abstract: A copper precursor composition contains: a first copper complex of an imine or a first cyclic amine coordinated to a first copper precursor compound; and, a second copper complex of a primary amine or a second cyclic amine coordinated to a second copper precursor compound. A copper precursor composition contains a copper complex of an imine coordinated to a copper precursor compound. The copper precursor composition is thermally degradable at a temperature lower than a comparable composition containing only primary amine copper complexes under otherwise the same conditions to produce a metallic copper film having a resistivity of about 200 ??-cm or less. Inks containing the copper precursor composition and a solvent may be deposited on a substrate and sintered to produce a metallic copper film. The substrate with the film thereon is useful in electronic devices.Type: GrantFiled: February 2, 2016Date of Patent: March 23, 2021Inventors: Chantal Paquet, Thomas Lacelle, Patrick R. L. Malenfant
