Abstract: A three-dimensional printing system includes a print engine and a controller. The controller in turn includes a processor coupled to a non-transient memory. The non-transient memory stores software instructions that when executed by the processor cause the controller to operate the print engine to fabricate a body. The body includes a three-dimensional arrangement of 3D articles that are pairwise coupled together. An individual pair of the arrangement of 3D articles includes a first article and a second article. A curved body couples a first surface of the first article to the second article. The curved body intersects the first surface to define a closed intersection curve that bounds a break surface. Along the closed intersection curve a surface of the curved body subtends an acute angle with the first surface.
