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: 11858199Abstract: In vat polymerization printer, light is projected from a digital light processing (DLP) light source towards an opening in a tank containing photo-curable liquid resin. A mask is used to filter the light from the DLP light source, the mask having pixels configurable to be individually transparent or opaque to portions of the light from the DLP light source. In a build area of the tank, the filtered light is used to cure the photo-curable liquid resin so as to form a layer of a partially formed object. The operation of the DLP light source is synchronized with the operation of the mask, such that light from the DLP light source with high intensity is transmitted through the transparent pixels of mask and light from DLP light source with low intensity is blocked by the opaque pixels of mask. The mask may enhance the resolution of DLP light source.Type: GrantFiled: September 13, 2022Date of Patent: January 2, 2024Assignee: NEXA3D INC.Inventor: Izhar Medalsy
