A substance delivery system has a three dimensional structure with outermost surface features and spaces for containing a substance. The substance has a level below the outermost surface features such that the substance is protected from inadvertent contact with external surfaces. The substance remains protected until the three dimensional structure is sufficiently deformed into a substantially two dimensional structure and the substance is thereby exposed to contact an external surface without compliance of the external surface being necessary. Deforming is preferably achieved by a compression force, wherein the outermost surface features of the three dimensional structure deform in a direction of the compression force. A method of making the three dimensional material includes the steps of coating a substance onto a forming surface, transferring the coating of substance from the forming surface to a piece of material, and forming the piece of material into a three dimensional structure on the forming surface while the substance is in contact with the forming surface.
