A conditioning agent (typically for use in repairing a flaw in a glazing panel) is contained in a sealed container which is itself disposed internally of a flexible outer walled container. Pressure applied to the outer flexible walled container can cause release of the conditioning agent from the internal conditioning agent container. The conditioning agent preparation may comprise a hygroscopic solvent (such as acetone) combined with one or more primer additives to prime the surface of the glazing panel for repair.

A tooling assembly for mounting a plurality of components, such as compressor blades, in a powder bed additive manufacturing machine to facilitate a repair process is provided. The tooling assembly includes component fixtures configured for receiving each of the compressor blades, a mounting plate for receiving the component fixtures, and a complementary fixture defining a plurality of voids within which the compressor blades are received when the complementary fixture is mounted to the mounting plate such that less powder is required to fill the powder bed.

A system includes a machine tool having a clamp. The system also includes a processing head configured to be temporarily held by the clamp of the machine tool. The processing head is also configured to deposit one or more media onto a workpiece. The processing head includes a guide configured to direct energy from an energy source onto the workpiece and/or the one or more media. The processing head also includes one or more supplies including one or more reservoirs within the processing head. The one or more reservoirs are configured to receive the one or more media, store the one or more media as the processing head is moved from one location to another location, and provide the one or more media.

A method of additively printing an extension segment on a workpiece includes pretreating a workpiece-interface of the workpiece using an energy beam emitted from an energy beam source of an additive manufacturing machine, providing a pretreated workpiece-interface having received a pretreatment, with the pretreatment remediating an aberrant feature of the workpiece and/or the workpiece-interface. The method further includes additively printing an extension segment on the pretreated workpiece-interface using an energy beam emitted from the energy beam source of the additive manufacturing machine. The aberrant feature includes one or more aberrant regions of the workpiece-interface having been determined from a digital representation of the workpiece-interface captured by a vision system. The pretreatment includes heat-conditioning at least a portion of the workpiece-interface including the one or more aberrant regions of the workpiece-interface.

A method for repairing composite components includes installing a plug within a feature defined by a composite component, with the plug being formed from one or more neutral materials. Furthermore, the method includes infiltrating the composite component with an infiltrant to densify a repair region of the composite component, with the plug blocking a flow of the infiltrant into the feature. Moreover, after infiltrating the composite component, the method includes removing the plug from the feature.

A machine tool arranged to deliver an energy source through a processing head onto a work-piece, wherein; the machine-tool has a clamping mechanism arranged to temporarily receive the processing-head, or another machining or processing-head, to process a work-piece; the processing-head comprising one or more guiding mechanisms arranged to direct the energy source onto a work-piece and a processing-head docking-manifold arranged to have connected thereto one or more media to be, in use, supplied to the processing-head to facilitate processing of the work-piece; wherein the processing-head docking-manifold allows the one or more media to be supplied to the processing-head when the processing-head is connected to the clamping mechanism; and wherein the machine-tool also comprises at least one mechanism arranged to move a supply docking-manifold into and/or out of connection with the processing-head docking-manifold such that when the two manifolds are connected the or each media is supplied to the processing head.

An additive manufacturing machine for repairing a component includes a build platform that supports the component and a powder dispensing assembly for selectively depositing additive powder over the build platform. A powder seal assembly includes a powder support plate positioned above the build platform and defining an aperture for receiving the component without contacting the component. An inflatable sealing element is operably coupled to the powder support plate around the aperture and is inflated to contact and seal against the component, thereby forming a support surface above the build platform upon which additive powder may be deposited.
