Abstract: A cellular material includes a continuous solid phase including an ordered ceramic material, the solid phase having a solid core including the ordered ceramic material. A composition for forming a cellular material includes: a first UV curable pre-ceramic monomer; a second UV curable pre-ceramic monomer; and a photoinitiator. A method of forming at least one ceramic waveguide includes: securing a volume of a composition including a UV curable pre-ceramic monomer; exposing the composition to a light source to form at least one polymer waveguide including a pre-ceramic material; and converting the pre-ceramic material of the polymer waveguide to a ceramic material to form a ceramic waveguide.

Abstract: A system for forming a micro-truss structure including a reservoir having walls and a flat bottom configured to hold a volume of a liquid photomonomer configured to form a photopolymer when exposed to light, a partially transparent mask secured to, or being, the bottom of the reservoir, a release layer on the mask configured to resist adhesion by the photopolymer, and a blocker positioned a first distance below the mask. The system also includes a light source positioned below the blocker configured to produce collimated light suitable for causing conversion of the photomonomer into the photopolymer, and to which the blocker is opaque, and a first mirror, oblique to the blocker, configured to reflect the light from the light source around the blocker and through the mask and into the reservoir. The blocker is positioned to block a straight path of light from the light source to the mask.

Abstract: Methods of manufacturing a structure having at least one plated region and at least one unplated region. The method includes plating a metal on a polymer structure having a first region accepting the metal and a second region unreceptive to the metal plating. The first region may include fully-cured polymer optical waveguides and the second region may include partially-cured polymer optical waveguides. The first region may include a first polymer composition and the second region may include a second polymer composition different than the first polymer composition.

Abstract: A system for fabricating micro-truss structures. A reservoir holds a volume of a liquid photomonomer configured to polymerize to form a photopolymer when exposed to suitable light such as ultraviolet light. A mask at the bottom of the reservoir includes a plurality of apertures. Light enters the reservoir through each aperture from several directions, forming a plurality of self-guided photopolymer waveguides within the reservoir. The light is supplied by one or more sources of collimated light. A plurality of mirrors may reflect the light from a single source of collimated light to form a plurality of collimated beams, that illuminate the photomonomer in the reservoir, through the mask, from a corresponding plurality of directions, to form a micro-truss structure including a plurality of self-guided waveguide members.

Abstract: The present invention relates to a micro-lattice and, more particularly, to an ultra-light micro-lattice and a method for forming the same. The micro-lattice is a cellular material formed of interconnected hollow tubes. The cellular material has a relative density in a range of 0.001% to 0.3%, and a density of 0.9 mg/cc has been demonstrated. The cellular material also has the ability to recover from a deformation exceeding 50% strain.

Abstract: Architected materials with superior energy absorption properties when loaded in compression. In several embodiments such materials are formed from micro-truss structures composed of interpenetrating tubes in a volume between a first surface and a second surface. The stress-strain response of these structures, for compressive loads applied to the two surfaces, is tailored by arranging for some but not all of the tubes to extend to both surfaces, adjusting the number of layers of repeated unit cells in the structure, arranging for the nodes to be offset from alignment along lines normal to the surfaces, or including multiple interlocking micro-truss structures.

Abstract: A sparse micro-truss structure having a series of unit cells arranged in an array is disclosed. Each of the unit cells includes a series of struts interconnected at a node. Adjacent unit cells are spaced apart by a gap. Spacing apart the adjacent unit cells is configured to reduce the sensitivity of the sparse micro-truss structure to premature mechanical failure due to buckling in one or more of the struts compared to related art micro-truss structures having a series of fully interconnected unit cells.
