System and Method for Manufacturing a Three-Dimensional Object from Freely Formed Three-Dimensional Curves

摘要

A three-dimensional object is manufactured by forming a series of three-dimensional formed curves of extruded material that together comprise the geometry of the surface of the object. The material is extruded from a nozzle that is positioned by a robotic arm under the control of a robotic controller. A computer that has a definition of the geometric surface generates commands to the robotic controller to cause it to sequentially form the series of formed curves that the computer calculates comprise the surface geometry.

1. A system for forming a three dimensional object with a three dimensional geometric surface comprising:
A nozzle with an outlet aperture adapted to emit a source material from the aperture; A positioning module adapted to position the nozzle in response to a positioning controller output, where the positioning controller is adapted to receive commands comprised of parameters defining at least one three dimensional curve paths, said at least one curve paths comprising the geometric surface, said positioning controller output being operatively connected to control the position of the nozzle by means of the positioning module.
