Zusammenfassung:	A method of manufacturing a three-dimensional (3D) article includes operating a print engine to fabricate a composite structure including the 3D article coupled to a support structure, removing the composite structure from the fluid tank, and peeling the inside surface of the sheath away from the outer surface of the article, peeling progressively breaks the plurality of strands. The support structure includes a conformal sheath having an inside surface that follows the outer surface of the 3D article with a gap between the inside surface of the sheath and the outer surface of the article, and a plurality of strands that span the gap and individually have opposed ends that are coupled to the inside surface of the sheath and the outer surface of the article to maintain the gap, the gap filled with the photocurable liquid ink.
