An alert is transmitted if the determined comparison measure of a layer is not within a defined range. A defined action is applied to the manufacturing process based on the transmitted alert.Type: GrantFiled: July 14, 2017Date of Patent: May 22, 2018Assignee: General Electric CompanyInventors: Adam McCann, Jacob Berlier, Li Zhang, Brandon Good

Patent number: 9649811Abstract: A method of additive manufacturing of a three-dimensional object is disclosed. The method comprises sequentially forming a plurality of layers each patterned according to the shape of a cross section of the object. In some embodiments, the formation of at least one of the layers comprises performing a raster scan to dispense at least a first building material composition, and a vector scan to dispense at least a second building material composition. The vector scan is optionally along a path selected to form at least one structure selected from the group consisting of (i) an elongated structure, (ii) a boundary structure at least partially surrounding an area filled with the first building material, and (iii) an inter-layer connecting structure.Type: GrantFiled: April 17, 2012Date of Patent: May 16, 2017Assignee: Stratasys Ltd.Inventor: Eduardo Napadensky
