Patent number: 11207836Abstract: The present application relates generally to systems and methods for using machine vision to provide information on one or more aspects of an additive fabrication device, such as calibration parameters and/or an object formed by the device or in the process of being formed by the device. According to some aspects, a method is provided for calibrating an additive fabrication device. According to some aspects, a method is provided for assessing at least a portion of an object formed using an additive fabrication device. According to some aspects, a method is provided for fabricating a second object in contact with a first object using an additive fabrication device. According to some aspects, an additive fabrication device configured to perform one or more of the above methods may be provided.Type: GrantFiled: July 30, 2019Date of Patent: December 28, 2021Assignee: Massachusetts Institute of TechnologyInventors: Javier E. Ramos, Pitchaya Sitthi-Amorn, Wojciech Matusik, Yuwang Wang

Patent number: 11155040Abstract: A closed-loop adaptive material deposition apparatus and method uses a scanning system to monitor an additively manufactured object as it is being fabricated and adapting the geometric shape and material composition of the subsequent layers based on the scan data. The scanning system repeatedly captures geometric and/or material information of a partially manufactured object with optional auxiliary objects inserted during the manufacturing process. Based on this information, the actual surface geometry and/or actual material composition is computed. Surface geometry may be offset and used as a slicing surface for the next portion of the digital model. The shape of the slicing surface may then be recomputed each time the system scans the partially fabricated object.Type: GrantFiled: October 25, 2019Date of Patent: October 26, 2021Assignee: Massachusetts Institute of TechnologyInventors: Wojciech Matusik, Allen S. Park, Javier E. Ramos, Kiril Vidimce
