Proximity correction in three-dimensional manufacturing

Abstract:

Methods and systems for printing accurate three-dimensional structures include printing an original three-dimensional structure according to an original three-dimensional model. The original three-dimensional model is adjusted to reduce measured differences between the printed three-dimensional structure and the original three-dimensional model, by adding material to the original three-dimensional model in proportion to an amount of thermal contraction in a region. An adjusted three-dimensional structure is printed according to the adjusted three-dimensional model.
