Patent number: 11884015Abstract: A system and method for facilitating separation of 3D-printed objects from build platforms. The principle of separation in the present invention involves a build platform configured to be removable or flexible or partially deformable, such that at least a portion of the build platform may be bent or tilted to separate the build platform from the 3D-printed object once the 3D-printing is completed. In some embodiments, a base assembly is adapted to magnetically move a build plate along a surface of the base assembly such that the build plate automatically self-aligns along a boundary of the base assembly and magnetically couples to the base assembly. In some embodiments, a build platform includes a flexible layer with a printable surface and a rigid layer coupled to the flexible layer so that applying a force on the flexible layer deforms a localized portion of the printable surface without deforming the rigid layer.Type: GrantFiled: January 31, 2022Date of Patent: January 30, 2024Assignee: SprintRay, Inc.Inventors: Amir Mansouri, Aayush Patel, Angali E. Daniels, Huijian Tian, Chonghuan Huang

Patent number: 11833756Abstract: The invention is generally a system for washing off residual resin from objects which are three-dimensionally (3D) printed through a vat polymerization (VP) process. Exemplary systems may include a solvent receptacle, a wash reservoir in fluid communication with the solvent receptacle, and a controller configured to pump a solvent from the solvent receptacle to the wash reservoir for washing off residual resin from a 3D-printed object. Exemplary methods may include pumping a first solution of a plurality of solvent solutions from the solvent receptacle to the wash reservoir, dispersing the first solution onto the 3D-printed object, pumping the first solution from the wash reservoir to the solvent receptacle, pumping a second solution of the plurality of solvent solutions from the solvent receptacle to the wash reservoir, and dispersing the second solution onto the 3D-printed object.Type: GrantFiled: February 23, 2022Date of Patent: December 5, 2023Assignee: SprintRay Inc.Inventors: Amir Mansouri, Huijian Tian, Shukun Ye, Hossein Bassir, Aayush Patel, Hang Ye

Publication number: 20230339190Abstract: The present subject matter is directed towards a system and a method for selectively post-curing a three-dimensional (3D-printed) object to attain variable properties. The system comprises a selective post-curing chamber coupled to a computer in communication with a database for accessing a digital model or data concerning the 3D-printed object. The chamber comprises a movable light source assembly and a mounting platform for supporting at least one 3D-printed object thereon. The computer includes one or more executable instructions for selectively emitting a curing light onto the 3D-printed object along a predetermined curing toolpath based on the digital model. The curing of the 3D-printed object along the predetermined curing toolpath generates variable properties along different regions of the 3D-printed object.Type: ApplicationFiled: June 29, 2023Publication date: October 26, 2023Inventors: Amir Mansouri, Hossein Bassir, Aayush Patel, Huijian Tian

Publication number: 20230278288Abstract: The invention is generally a system for drying, recycling, and washing off residual resin from three-dimensionally (3D) printed objects. Exemplary systems may include a wash reservoir, a fan module, and one or more air exchange vents. The wash reservoir contains a wash solvent and a propeller fully or partially submerged into the wash solvent. The propeller splashes the wash solvent upwards to disperse on the 3D printed object, thereby largely washing away the resin residue present in the 3D printer object. The fan module is connected to the wash reservoir to create a positive or negative air pressure inside the wash reservoir, thereby redirecting the airflow to the wash reservoir. The air exchange vents are provided between a splash guard and a platform/lid of the wash reservoir to act as an air intake when the fan module blows air out of the wash reservoir and as an exhaust vice versa.Type: ApplicationFiled: February 23, 2023Publication date: September 7, 2023Inventors: Amir Mansouri, Hossein Bassir, Huijian Tian, Shukun Ye, Aayush Patel, Hang Ye

Exemplary systems may include a system for washing off residual printing material from a surface of a 3D-printed. In an exemplary embodiment, a chamber is adapted to receive the 3D-printed object and a printing material disruption module is adapted to disrupt a composition of residual printing material on a surface of the 3D-printed object. Additionally, a washing force module may be adapted to apply a washing force field to the 3D-printed object and wash off the residual printing material.Type: ApplicationFiled: February 23, 2023Publication date: July 6, 2023Inventors: Amir Mansouri, Hossein Bassir, Huijian Tian, Shukun Ye, Aayush Patel, Hang Ye

Publication number: 20230202110Abstract: The invention is a system for drying, recycling, and washing off residual resin from 3D-printed objects. Some aspects of the invention include a system for recycling solvents used to clean the 3D-printed objects in a washing chamber. The recycling system may include one or more solvent reservoirs that store a solvent for cleaning residual 3D-printing material off of 3D-printed objects, a wash chamber adapted to clean the 3D-printed objects, and a solvent recycling module. The solvent recycling module receives a saturated solvent from the one or more solvent reservoirs, evaporates or condenses the saturated solvent to remove residual 3D-printing material from the saturated solvent, and returns clean solvent to the one or more solvent reservoirs of the system.Type: ApplicationFiled: February 23, 2023Publication date: June 29, 2023Inventors: Amir Mansouri, Hossein Bassir, Huijian Tian, Shukun Ye, Aayush Patel, Hang Ye
