Abstract: A method of manufacturing a three-dimensional (3D) object may include fabricating a support structure and fabricating the 3D object on the support structure, wherein the support structure contacts the 3D object at a support region of the 3D object. The method further includes overcuring the 3D object at an overcure region of the 3D object, wherein the overcure region is distinct from the support region, and removing the support structure from the 3D object. After removal of the support structure, a support mark remains on the 3D printed object where the support structure had contacted the 3D object, wherein the overcure region of the 3D object projects past the support mark.

Abstract: Systems, methods, and devices for post-processing additively manufactured objects are disclosed herein. In some embodiments, a method includes receiving a plurality of additively manufactured objects (404) having excess material thereon. The method can include removing the excess material from the plurality of additively manufactured objects by rotating the plurality of additively manufactured objects. The method can also include adjusting an environmental temperature while rotating the plurality of additively manufactured objects according to a dynamic temperature profile that facilitates removal of the excess material from the plurality of additively manufactured objects. The dynamic temperature profile can include (a) a first temperature configured to decrease a viscosity of the excess material, and (b) a second temperature configured to increase a stiffness of the plurality of additively manufactured objects.
