Claim of US Patent No. 9,096,722

1. A monomeric formulation for fabrication of microlattice structures, the monomeric formulation comprising:
a plurality of monomers comprising thiol;
a first photoinitiator configured to substantially activate above a wavelength of light; and
a second photoinitiator configured not to substantially activate above the wavelength of light and to substantially activate
below the wavelength of light,

wherein a concentration of the second photoinitiator in the monomeric formulation is greater than that of the first photoinitiator,
the first photoinitiator being about 0.01% to about 0.1% by weight of the monomeric formulation, and the second photoinitiator
being about 0.1% to about 1% by weight of the monomeric formulation.
