Patent number: 11919262Abstract: The present application relates to a method for post-processing a powder-based additively manufactured part. The method comprising the steps of providing a powder-based additively manufactured part, the additively manufactured part comprising a material having a melting point, providing a fluid for processing the additively manufactured part in order to improve the surface finish of the additively manufactured part, wherein the fluid comprises at least one solvent selected from an organic ester, an aromatic organic compound or an acetal, a heating step, wherein the fluid is heated; and an application step, wherein the heated fluid is applied to a surface of the additively manufactured part. It has been found this process can help to improve the surface finish of the additively manufactured part, e.g. resulting in a less rough (i.e. smoother) surface finish.Type: GrantFiled: March 3, 2021Date of Patent: March 5, 2024Assignee: Additive Manufacturing Technologies LimitedInventors: Joseph Crabtree, Konstantin Rybalcenko, Ioannis Anastasopoulos

Publication number: 20230241684Abstract: The present application relates to a method and system for removing material from an additively manufactured part. The method comprises providing an additively manufactured part comprising a part section and a support structure, providing a material having an expansible volume, carrying out an application step, wherein the material is applied to the additively manufactured part and carrying out a de-coupling step, wherein the material is expanded from a first, unexpanded, state to a second, expanded, state so as to generate a separating force for de-coupling the part section and the support structure.Type: ApplicationFiled: June 18, 2021Publication date: August 3, 2023Inventors: Konstantin Rybalcenko, Joseph Gwilliam Crabtree

Publication number: 20220250154Abstract: According to the present disclosure, there is provided a method for smoothing a surface of an additively manufactured metal part. The method comprises applying a chemical to a stepped surface of an additively manufactured part to at least soften a binder material supporting unprocessed powder particles of the part and allowing the powder particles at the surface to flow under the influence of gravity into recesses defined by the stepped surface to thereby reduce a roughness of the surface. Advantageously, it has been found that the afore-described method is able to provide a part having an improved surface smoothness.Type: ApplicationFiled: June 9, 2020Publication date: August 11, 2022Applicant: ADDITIVE MANUFACTURING TECHNOLOGIES LIMITEDInventors: Joseph Gwilliam Crabtree, Konstantin Rybalcenko, Andre Gaio
