Claim 7:
8. A system comprising:
a fabrication computing system having one or more processors and memory storing instructions that, when executed by the one or more processors, cause the one or more processors to:
receive a first digital model of a first dental aligner configured to move one or more teeth based on a generated treatment plan;
receive a second digital model of a second dental aligner configured to move one or more teeth based on a second generated treatment plan;
prepare the first digital model of the first dental aligner for manufacturing, wherein preparing the first digital model of the first dental aligner includes modifying the first digital model by adding one or more support structures to the first digital model to be formed with the first dental aligner; and
prepare the second digital model of the second dental aligner for manufacturing, wherein preparing the second digital model of the second dental aligner includes analyzing a size or shape of the second digital model of the second dental aligner and a size or shape of the first digital model of the first dental aligner;

a 3D printing fabrication system configured to print the first dental aligner with the one or more support structures and the second dental aligner simultaneously; and
a laser system having one or more processors and memory storing instructions that, when executed by the one or more processors, cause the one or more processors to:
orient, by a fixture, the first dental aligner with the one or more support structures, wherein orienting the first dental aligner includes locating one or more features of the first dental aligner relative to the laser system; and
cut, by a laser beam, an interface between the support structures and the first dental aligner to remove the one or more support structures from the first dental aligner.
