Abstract: Wearable and implantable devices that are used to support human anatomy and are formed using additive manufacturing are provided. Systems and methods for performing additive manufacturing allow for the formulation of a mesh material that has localized stiffness and slack in regions to best serve the needs of the patient. For example, regions of the mesh material can be designed to rigidly support portions of human anatomy, such as injured tissue, while regions of the mesh material adjacent to the injured tissue can be designed to closely mimic movement of the relevant human anatomy. For example, the mesh material can be formed in a manner such that it does not fold in those regions, and therefore is not obtrusive. The present disclosure allows for control of toolpaths when printing fibers used to form the devices. Other devices, as well as systems and methods for creating the same, are also provided.
