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.

A method for producing an injection molded and anti-skid mat providing a lower mold half and an enclosing upper mold half, the mold halves defining therebetween an interior cavity which is a negative of the mat to be produced. A cavity defining surface is configured in the bottom mold half with locations for preplacement of a plurality of underside adhering portions. A flowable plasticized/rubberized material is communicated through a channel in at least one of the mold halves in order to fill the interior cavity, the material setting and cooling prior to removing the upper mold half and the formed mat.

A forming method of a composite magnetic sheet. The forming method comprises a preparing step, a forming step and a heat-treating step. In the preparing step, magnetic slurry is prepared by mixing at least a soft magnetic powder having a flat shape, a first resin having a solid component and a second resin having a solid component, weight loss of the solid component of the first resin being 4.0% or less at 220° C., weight loss of the solid component of the second resin being 5.0% or more at 220° C. In the forming step, the magnetic slurry is formed into an intermediate body having a sheet-like shape. In the heat-treating step, the intermediate body is heat-treated at a heat-treatment temperature between 220° C. and 400° C. (both inclusive).
