Abstract: Monomeric formulations appropriate for creating self-propagating polymer optical waveguides, and methods for their fabrication, are disclosed. Multiple polymer waveguides can be fabricated simultaneously into a three-dimensional micro-truss structure, while avoiding significant polymerization outside the confines of the illuminated region. The formulations described to accomplish this controlled polymerization include species containing one or more unsaturated carbon-carbon bonds capable of being free-radical polymerized in the presence of photoinitiator and either a radical inhibitor species or a solvent, or both. The radical inhibitor and/or solvent are included to minimize heat buildup and thermal decomposition of initiator. This invention enhances the versatility of the chemistry by significantly increasing the number of chemical building blocks available for micro-truss fabrication.

Abstract: A micro-truss sheet having material properties varying across the sheet. The sheet may include a plurality of truss members intersecting at nodes. The diameter of the truss members at one point in the sheet may differ from the diameter of the truss members at another point in the sheet. In one embodiment the spacing between adjacent truss members may be different in one part of the sheet from the spacing between adjacent truss members in another part of the sheet.
