Patent number: 11926103Abstract: An approach to precision additive fabrication uses jetting of cationic compositions in conjunction with a non-contact (e.g., optical) feedback approach. By not requiring contact to control the surface geometry of the object being manufactured, the approach is tolerant of the relative slow curing of the cationic composition, while maintaining the benefit of control of the deposition processes according to feedback during the fabrication processes. This approach provides a way to manufacture precision objects and benefit from material properties of the fabricated objects, for example, with isotropic properties, which may be at least partially a result of the slow curing, and flexible structures, which may not be attainable using conventional jetted acrylates.Type: GrantFiled: November 12, 2021Date of Patent: March 12, 2024Assignee: Inkbit, LLCInventors: Wenshou Wang, Gregory Ellson, Yan Zhang, Desai Chen, Javier Ramos, Wojciech Matusik, Kiril Vidimce

Patent number: 11518109Abstract: A method for managing the temperature of three-dimensional object during additive manufacturing includes depositing material on a partial fabrication of the three-dimensional object, determining thermal properties of the three-dimensional object after depositing the material, and controlling cooling of the object according to said thermal properties. In some examples, the determining of the thermal properties includes determining a temperature variation across the object and controlling position-dependent cooling of the object in a feedback arrangement. Resulting uniform temperature of the object under fabrication can improve dimensional accuracy and material properties of the object.Type: GrantFiled: October 30, 2020Date of Patent: December 6, 2022Assignee: Inkbit, LLCInventors: Wojciech Matusik, Javier Ramos, Aaron Weber

Publication number: 20220379547Abstract: A method includes manufacturing a kernel that comprises a quantity of a phase-change material and heating the thermoplastic past a softening temperature thereof. This softening temperature is greater than the phase-change material's melting temperature. The method continues with pressing this heated thermoplastic onto a contact surface of the kernel and the thermoplastic to cool to below its softening temperature. As a result, the thermoplastic assumes a profile that depends, at least in part, on the contact surface's profile. The method continues with separating the kernel from the thermoplastic.Type: ApplicationFiled: June 21, 2022Publication date: December 1, 2022Inventors: Javier Ramos, Richard Woudenberg, Wojciech Matusik

Patent number: 11364680Abstract: A manufacturing method includes using an additive manufacturing process to form a first object. The first object includes layers, among which is a first layer that comprises a first material and a second material. The first material surrounds the second material within the first layer. Both materials are solids that transition into liquids at corresponding first and second temperatures, the first temperature being lower than the second temperature. The method includes, after having formed the first object, exposing the first object to a temperature that is between the first temperature and the second temperature such that the first material melts, thereby leaving behind a second object, the second object comprising the second material.Type: GrantFiled: May 26, 2021Date of Patent: June 21, 2022Assignee: Inkbit, LLCInventors: Javier Ramos, Richard Woudenberg, Wojciech Matusik

Publication number: 20210394436Abstract: An approach to improving optical scanning increases the strength of optical reflection from the build material during fabrication. In some examples, the approach makes use of an additive (or a combination of multiple additives) that increases the received signal strength and/or improves the received signal-to-noise ratio in optical scanning for industrial metrology. Elements not naturally present in the material are introduced in the additives in order to increase fluorescence, scattering or luminescence. Such additives may include one or more of: small molecules, polymers, peptides, proteins, metal or semiconductive nanoparticles, and silicate nanoparticles.Type: ApplicationFiled: May 4, 2021Publication date: December 23, 2021Inventors: Wojciech Matusik, Gregory Ellson, Desai Chen, Javier Ramos, Davide Marini, Aaron Weber
