Feedstocks for additive manufacturing are provided. The feedstock may include a matrix material, and one or more capsules disposed in the matrix material, wherein the one or more capsules are configured to be removable from a surface portion when the matrix material is solidified to form one or more cavities in the surface portion. Methods of depositing the feedstocks and objects formed from the feedstocks are also provided.

A method of modifying a coating material includes applying a fluid including a population of particles to a wet coating material disposed on a substrate. The method also includes drying the wet coating material so as to give rise to a coated article, where the particles are at least partially embedded in a surface of the dried coating material. The particles can be metallic nanowires, and a loading of the metallic nanowires in the dried coating material can be above an electric percolation threshold.

A composite structure comprising a matrix and a reinforcement. The matrix comprises a substantially nonconductive material. The reinforcement comprises a conductive material. The reinforcement is located within the matrix to form a composite layer. A portion of the reinforcement is exposed at a surface of the composite layer such that electrical conductivity of the composite layer is increased in a direction substantially perpendicular to the composite layer.

A 3-D (three dimensional) printing system is provided that includes a customized matrix having suitable material properties and geometric patterning to facilitate filling and retention of one or more filler material. The customized matrix defines the geometry and shape of the object. A filler mechanism that fills the customized matrix with one or more filler materials. The one or more filler materials retained within the customized matrix are cured or solidified to produce the object.
