Abstract: Systems and methods for combatting shrinking forces within drying photopolymers of additive manufacturing processes are disclosed herein. According to at least some embodiments, layers of an additive manufacturing build are split into core components and shell components. Magnetically active additives within the photopolymer resin are then aligned in a first plane while the core section is cured, and a second plane while the outer shell section is cured. According to at least some embodiments, the first plane and the second plane are perpendicular.
