Abstract: Systems, devices, and methods for additive manufacturing of objects are provided. In some embodiments, a system for fabricating an object includes a flexible substrate, a carriage coupled to the flexible substrate, an actuator, at least one recoater supported by the carriage, and an energy source. The flexible substrate can be configured to carry a precursor material. The carriage can vertically displace an active region of the flexible substrate away from a remaining region of the flexible substrate and toward a build platform. The actuator can be configured to move the carriage relative to the flexible substrate. The at least one recoater can be configured to apply the precursor material to the flexible substrate. The energy source can be configured to output energy toward the precursor material at the active region of the flexible substrate to form a portion of an object on the build platform.
