Abstract: An additively manufactured (AM) structure includes a removal plane extending therein defining an object thereabove. The AM structure also includes at least one datum structure coupled relative to the AM structure. Each datum structure includes a vertical reference plane for guiding a cutting element to remove the object from a remaining portion of the AM structure through the removal plane. The vertical reference plane is horizontally coplanar with the removal plane of the AM structure. The datum structures allow for accurate object cuts regardless of whether an AM build platform is horizontal or non-planar.
