    摘要: A method of quality assurance of an additive manufacturing build process. An additive manufacturing system is operated to perform a build process by building a part on a build platform, the part being built by forming a series of layers of metallic material on the build platform. The metallic material melts and solidifies during the build process thereby bonding the part to the build platform and creating thermally induced stress in the part which tends to distort the build platform. During the build process, a parameter is measured which is related to the thermally induced stress in the part to generate measurement data. The measurement data is stored and analysed to determine whether a defect has formed during the build process. A warning is generated if the analysis of the stored measurement data concludes that a defect has formed during the build process. The warning includes an indication of a position in the part.

    摘要: A composite assembly with a laminate of fibre plies impregnated with a laminate matrix material is disclosed having pad of fibre plies impregnated with a pad matrix material, and a part with a body with protrusions which extend from the body and penetrate at least some of the fibre plies of the pad. The pad is bonded to the laminate by a stepped lap joint or a scarf joint. The assembly is manufactured by pressing the protrusions into the pad, and after the protrusions have been pressed into the pad, curing a pad matrix material impregnating the pad, and bonding the pad to the laminate.

    摘要: A method of additive manufacturing and heat treatment. A substrate is secured to a fixture and an additive manufacturing system is operated to perform a build process by building a part on the substrate secured to the fixture, the part being built by forming a series of layers of metallic material on the substrate, the metallic material melting and solidifying during the build process thereby bonding the part to the substrate and creating thermally induced stress in the part. The part, the substrate and the fixture are moved together from the additive manufacturing system to a heat treatment system, wherein the substrate remains secured to the fixture and the part remains bonded to the substrate as they are moved. The heat treatment system is operated to perform a heat treatment process by heating the part, the substrate and the fixture together thereby relieving the thermally induced stress in the part, the substrate remaining secured to the fixture during the heat treatment process. Finally the substrate is released from the fixture and the part and the substrate are removed from the fixture. The part remains bonded to the support as they are removed from the fixture.

    摘要: A method of manufacturing an object. A thermoplastic matrix material is melted to transform it into liquid matrix material. The liquid matrix material is fed into a chamber via one or more matrix inlets. A fibre is also fed into the chamber via a fibre inlet. The fibre in the chamber is contacted by the liquid matrix material. A coated fibre is extruded from an extrusion outlet of the chamber onto a substrate, the coated fibre comprising the fibre with a coating of the liquid matrix material, the substrate comprising a previously extruded coated fibre. The fibre moves in and out of the chamber at the same velocity relative to the chamber. The coating fuses with the previously extruded coated fibre and solidifies after it has fused with the previously extruded coated fibre. Relative movement is generated between the extrusion outlet and the substrate as the coated fibre is extruded from the extrusion outlet.
