Patent number: 11919233Abstract: Various embodiments provide a method of additively manufacturing a part including depositing a layer of a powder on a working surface, depositing a binder solution on the layer of the powder at first locations, and depositing a sintering aid solution on the layer of the powder at second locations. The sintering aid solution comprises a sintering aid in a solvent. In various embodiments, the sintering aid enables an increased brown strength as compared to parts containing unbound powder. The method enables binders that provide high green strength to be used at the edges of the part, while also balancing a shortened debind time with an increased brown strength. Embodiments in which binder solution is deposited according to a predetermined pattern at second locations are also described.Type: GrantFiled: August 17, 2022Date of Patent: March 5, 2024Assignee: General Electric CompanyInventors: Mary Kathryn Thompson, Arunkumar Natarajan, Kwok Pong Chan, Vadim Bromberg, Xi Yang, Ananda Barua, William C.
