3D PRINTED OBJECTS WITH SELECTIVE OVERCURE REGIONS

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.
