Abstract
A method of additive three-dimensional object production includes depositing liquefied material to produce two roads and placing an extruder tip having a bottom surface that surrounds an orifice such that one portion of the bottom surface is sealed against one of the two roads and another part of the bottom surface is sealed against the other of the two roads and the orifice is positioned over a space between the two roads. Liquefied material is then extruded through the orifice to fill the space between the two roads.
