| 摘要 | A method for improving part quality for a printed three-dimensional part, the method comprising moving a print head nozzle along a substantially linear segment of a tool path at a tip height above a previous layer of the three-dimensional part while extruding a flowable material, and producing an extruded road from the extruded flowable material having a road height above the previous layer, where the tip height is greater than the road height due at least in part to draw on the extruded road. | ||

| 主权项 | 1. A method for improving part quality for a printed three-dimensional part, the method comprising: providing a print head retained by an extrusion-based additive manufacturing system, the print head comprising a nozzle; and moving the nozzle along a substantially linear segment of a tool path at a tip height above a previous layer of the three-dimensional part while extruding a flowable material; producing an extruded road from the extruded flowable material having a road height above the previous layer, and wherein the tip height ranges from about 150% to about 250% of the road height due at least in part to draw on the extruded road, wherein the printed three-dimensional part is substantially free of surface cresting. | ||
