Abstract
A method and apparatus is disclosed for additive manufacturing and three-dimensional printing, and specifically for extruding tubular objects. A print head extrudes a curable material into a tubular object, while simultaneously curing the tubular object and utilizing the interior of the cured portion of the tubular object for stabilizing and propelling the print head.
