The present disclosure provides three-dimensional (3D) printing systems, devices, apparatuses, methods, and non-transitory computer readable media associated with 3D printing systems that include dynamically movable optical components operatively coupled with a translation mechanism, e.g., comprising an optical image generator, a detector, or an optical assembly configured to direct a printing agent such as an energy beam. The present disclosure includes resulting objects printed in the 3D printing systems, as well as various other components relating to a 3D printing system.
