With 3D printed objects, greater strength can be accomplished. This is due to the perimeters encapsulating the entire object and passing loads throughout without disruptions in the path. The Infill that is inside also assists in taking the load and spreading it through the entire print and thus reducing stress concentrations. This enables prints to be exceptionally strong in compression, and to a lesser degree, tension. Depending on the infill rates and material used on a print, the forces necessary to cause damage might be well in excess of what an average adult could exert.
