Combined process for building three-dimensional models

A method for building a three-dimensional model, the method comprising:

• selectively removing at least a portion of at least one material feedstock to form a plurality of base seeds, wherein at least a portion of the plurality of base seeds each comprise a target surface;
• depositing a material onto the target surfaces to form at least one surface feature selected from the group consisting of topographical features, color patterns, coatings, and combinations thereof;
• separating the plurality of base seeds from the at least one material feedstock;
• and
• assembling the plurality of base seeds to form at least a portion of the three-dimensional model, wherein the at least one surface feature constitutes at least a portion of an exterior surface of the three-dimensional model.

A system for building a three-dimensional model, the system comprising:

• at least one subtractive removal station configured to form a plurality of base seeds from at least one material feedstock, wherein each of the plurality of base seeds comprises a mating surface, and at least one of the seeds comprises a target surface;
• at least one additive deposition station configured to deposit at least one material on at least a portion of the target surface to provide a coated target surface;
• and
• at least one assembly station comprising at least one robotic manipulator configured to combine the plurality of base seeds to form at least a portion of the three-dimensional model, wherein the coated target surface constitutes at least a portion of an exterior surface of the three-dimensional model.
