Abstract
Aspects of this disclosure include a method for repairing a component having narrow passage, a three-dimensional printer, and composition for three-dimensional printing. One embodiment of the method may comprise mixing a filler material for three-dimensional printing with a carrier fluid, and applying a controlled electromagnetic field to bias the filler material towards a repair location in a narrow passage of a component. The method may further comprise coating a ferromagnetic material with the filler material to form a microcapsule, wherein the ferromagnetic material is adapted to interact with the controlled electromagnetic field to attract the microcapsule to the repair location. 3D printing techniques may be used to coat the ferromagnetic core with the filler material.
