1. A method of forming a three-dimensional structure, said method comprising one or more of the following:
(i) curing a first composition to form a first layer, said first composition comprising at least 50% by weight of a polymer that comprises the following monomers:

OG Complex Work Unit Chemistry
and
a crystallization disruptor monomer comprising:

OG Complex Work Unit Chemistry
where:
each R1 can be the same or different and is chosen from alkyls and fluoroalkyls;
R2 is chosen from alkyls; and
each R3 can be the same or different and is chosen from phenyl, alkyls, and fluoralkyls, wherein at least one R3 is phenyl, ethyl, or a fluoroalkyl;
(ii) curing a second composition to form a second layer on said first layer, wherein said first and second compositions can be the same as or different from one another; and
(iii) repeating (ii) one or more times with further compositions that can be the same as the first composition or different from the first composition so as to form one or more additional layers, wherein (ii) or (iii) results in the formation of the three-dimensional structure.
