Patent number: 11155071Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize support structure in the process of building objects that may be removed by rotating the support structure to a second orientation before removal, as well as novel support structures to be used within these AM processes. The support structures are fabricated in a first orientation and then rotated to the second orientation. The support structures are removed by passing through an outlet of the object.Type: GrantFiled: July 16, 2019Date of Patent: October 26, 2021Assignee: General Electric CompanyInventors: Zachary David Fieldman, Daniel Joerger, Neal Dunham

Patent number: 10799951Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize conformal support structures in the process of building objects, as well as novel conformal support structures to be used within these AM processes. The conformal support structures include a first portion that extends from a platform to a concave upward surface of the first portion that is below a downward facing convex surface of the object. The concave upward surface corresponds to the downward facing convex surface. The downward facing convex surface of the object is separated from the concave upward surface of the first portion by at least one portion of unfused powder.Type: GrantFiled: February 11, 2016Date of Patent: October 13, 2020Assignee: GENERAL ELECTRIC COMPANYInventor: Daniel Joerger
