SYSTEMS, DEVICES, AND METHODS FOR PRECISION LOCATING AND ASSEMBLY OF ADDITIVELY MANUFACTURED COMPONENTS
Methods, systems, and devices for precision locating additively manufactured components for assembly and/or post processing manufacturing are provided for herein. In some embodiments, at least one component can be additively manufactured to include one or more kinematic features on one or more surfaces of the component.

Alternatively, the kinematic feature(s) can be configured to engage complementary kinematic feature(s) associated with a post-processing machine such that the one or more post-processing actions can be performed on the component after the component is precisely located with respect to the machine by way of the kinematic features of the component and associated with the machine. A variety of systems and methods that utilize kinematic features are also provided.
