1. A method of making a tiled composition comprising the steps of:
a. contacting a first portion of a photoactive pre-polymer with a volume of radiation from a radiation source sufficient to form a first tile;
b. translating the radiation source to a second portion of the photoactive pre-polymer, adjacent to the first portion of the photoactive pre-polymer,
i. wherein the second portion of the photoactive pre-polymer overlaps with the first portion of the previously irradiated photoactive pre-polymer at an overlap region;
c. contacting the second portion of the photoactive pre-polymer with a sufficient volume of radiation to form a second tile; and
d. optionally conducting additional translating and contacting steps to form additional adjacent tiles;
e. wherein each overlap region is at each radiation contacting step is contacted with a fractional amount of radiation relative to the radiation contacting the first portion and the second portion, such that the sum of radiation exposure at each overlap region through each contacting step is substantially similar to the radiation exposure of the first portion and the second portion that form the first tile and second tile; and
wherein the radiation is provided by volumetric beam shaping.
