A method of forming a three-dimensional composite material, the method comprising: securing a volume of a photo-monomer;securing a mask between at least one collimated light source and the volume of the photo-monomer, the mask having a plurality of apertures;directing a collimated light beam from the at least one collimated light source to the mask for a period of exposure time such that a portion of the collimated light beam passes through the mask and is guided by the plurality of apertures into the photo-monomer to form a plurality of waveguides through a portion of the volume of the photo-monomer;removing any uncured photo-monomer to leave behind a three-dimensional ordered open-cellular microstructure to define an open volume and a structure of a first continuous material of the three-dimensional composite material; andplacing a second continuous material in the open volume to substantially fill the open volume of at least one cell defined by the first continuous material,wherein the second continuous material and the first continuous material share an interface between each other and have physical properties differing from each other, andwherein the interface is everywhere continuous. 2. The method of claim 1, wherein the first continuous material is formed from a first material selected from the group consisting of a polymer material, a carbon material, a metal material, and a ceramic material, and wherein the second continuous material is formed from a second material selected from the group consisting of a polymer material, a carbon material, a metal material, and a ceramic material. 3. The method of claim 2, wherein the metal material of the first material or the second material is formed by coating at least one surface of the three-dimensional ordered open-cellular microstructure with an aqueous solution comprising a metal salt and reducing the aqueous solution on the at least one surface. 4. The method of claim 2, wherein the metal material of the first material or the second material is formed by electroplating and/or electroless plating of a metal selected from the group consisting of nickel (Ni), copper (Cu), gold (Au), silver (Ag), ruthenium (Ru), platinum (Pt), rhodium (Rh), cobalt (Co), iron (Fe), zinc (Zn), and combinations thereof. 5. The method of claim 2, wherein the ceramic material of the first material or the second material is formed by: coating the three-dimensional ordered open-cellular microstructure with a ceramic gelcasting solution; andpolymerizing the ceramic gelcasting solution by adding a catalyst to the ceramic gelcasting solution such that the ceramic gelcasting solution is solidified, wherein the ceramic gelcasting solution comprises a dispersed monomer; andremoving the dispersed monomer by heating the coated three-dimensional ordered open-cellular microstructure. 6. The method of claim 2, wherein the ceramic material of the first material or the second material is formed by: forming a green body by filling the open volume of the three-dimensional ordered open-cellular microstructure with a ceramic slurry; andheating the green body to provide sintering and additional mechanical strength. 7. The method of claim 2, wherein the ceramic material of the first material or the second material is formed by: coating the three-dimensional ordered open-cellular microstructure with a solution comprising a preceramic polymer; andheating the coated three-dimensional ordered open-cellular microstructure in an inert environment. 8. The method of claim 1, wherein at least one of the first continuous material or the second continuous material is formed by performing chemical vapor deposition of a material selected from the group consisting of silicon carbide, silicon nitride, hafnium carbide, chromium carbide, boron nitride, boron carbide, aluminum oxide, titanium, titanium diboride, titanium nitride, zirconium dioxide, titanium carbide, titanium carbonitride, tantalum, tantalum carbide, tantalum nitride, nobelium, and combinations thereof. 9.

The method of claim 1, wherein the first continuous material and the second continuous material are both solid. 16. A method of forming a three-dimensional composite material, the method comprising: securing a volume of a photo-monomer;securing a mask between at least one collimated light source and the volume of the photo-monomer, the mask having a plurality of apertures;directing a collimated light beam from the at least one collimated light source to the mask for a period of exposure time such that a portion of the collimated light beam passes through the mask and is guided by the plurality of apertures into the photo-monomer to form a plurality of waveguides through a portion of the volume of the photo-monomer;removing any uncured photo-monomer to leave behind a three-dimensional ordered open-cellular microstructure to define an open volume and a structure of a first continuous material of the three-dimensional composite material; andplacing a second continuous material and a third continuous material in the open volume to substantially fill the open volume of at least one cell defined by the first continuous material,wherein the first continuous material and the third continuous material share a first interface between each other and have physical properties differing from each other, and the first interface between the third continuous material and the second continuous material is everywhere continuous, andwherein the third continuous material and the second continuous material share a second interface between each other and have physical properties differing from each other, and the second interface between the third continuous material and the second continuous material is everywhere continuous. 17. The method of claim 16, wherein the first continuous material is formed from a first material selected from the group consisting of a polymer material, a carbon material, a metal material, and a ceramic material, wherein the second continuous material is formed from a second material selected from the group consisting of a polymer material, a carbon material, a metal material, and a ceramic material, and wherein the third continuous material is formed from a third material selected from the group consisting of a polymer material, a carbon material, a metal material, and a ceramic material. 18.
