Patent ID: 8663539

Claim:
A method of manufacturing a three-dimensional micro-truss structure, the method comprising: exposing a volume of photo-monomer to collimated light through a mask, the collimated light passing through a plurality of first apertures of the mask at a non-perpendicular angle with respect to the mask; forming a plurality of angled polymer waveguides into the photo-monomer at the non-perpendicular angle to form the three-dimensional micro-truss structure; exposing the volume of photo-monomer to collimated light through the mask, the collimated light passing through a plurality of second apertures of the mask in a direction perpendicular to the mask; and forming a plurality of vertical polymer waveguides into the photo-monomer in the direction perpendicular to the mask to further foam the three-dimensional micro-truss structure, at least one of the plurality of vertical polymer waveguides interpenetrating at least one of the plurality of angled polymer waveguides.
