A three-dimensional (3-D) printer comprising: an intermediate transfer belt; a first photoreceptor transferring a first material to said ITB; a second photoreceptor transferring a second material to said ITB, said first material is the same as said second material except said first material includes a photoinitiator and said second material does not include said photoinitiator; a platen moving relative to said ITB to make contact with said ITB, said ITB transferring successive layers of said first material and said second material to said platen each time said platen contacts said ITB; a heater heating said platen and heating a portion of said ITB that is adjacent said platen to a glass transition temperature of said first material and said second material prior to said platen contacting said ITB, said heater further heating said first material and said second material on said platen to a temperature between said glass transition temperature and a melting temperature of said first material and said second material after said ITB transfers said first material and said second material to said platen to fuse said first material and said second material to previously transferred material on said platen; and a light exposing said first material and said second material on said platen after each time said platen contacts said ITB to crosslink polymers of said first material without crosslinking polymers of said second material, said polymers of said first material being crosslinked and said polymers of said second material not being crosslinked makes said second material selectively soluble in different solvents relative to said build material. an intermediate transfer belt; a first photoreceptor transferring a first material to said ITB; a second photoreceptor transferring a second material to said ITB, said first material is the same as said second material except said first material includes a photoinitiator and said second material does not include said photoinitiator; a platen moving relative to said ITB to make contact with said ITB, said ITB transferring successive layers of said first material and said second material to said platen each time said platen contacts said ITB; a heater heating said platen and heating a portion of said ITB that is adjacent said platen to a glass transition temperature of said first material and said second material prior to said platen contacting said ITB, said heater further heating said first material and said second material on said platen to a temperature between said glass transition temperature and a melting temperature of said first material and said second material after said ITB transfers said first material and said second material to said platen to fuse said first material and said second material to previously transferred material on said platen; and a light exposing said first material and said second material on said platen after each time said platen contacts said ITB to crosslink polymers of said first material without crosslinking polymers of said second material, said polymers of said first material being crosslinked and said polymers of said second material not being crosslinked makes said second material selectively soluble in different solvents relative to said build material.
