Thinking of spacetime as a 4-dimensional manifold might be comforting , but if the object is a stationary object then it has no inherent time axis worth describing. With regards to describing objects within Spacetime, time is only useful as a descriptor when the object is in motion relative to a specific Frame, to describe that motion. We could develop an analysis of the effects of time upon the materials perhaps, but a 3D-printed cube only experiences motion over time if something else moves it.
