【Abstract】 This paper analyzes the reverse engineering and rapid prototyping technologies. Rapid tooling/parts manufacturing technology is proposed. The Unigraphics software is employed to reconstruct the 3D solid model of the data sets of 3D points gained by 3D scanning, then the solid model is transformed to STL surface model needed by rapid prototyping. The rapid prototype is fabricated by LOM, and then combined with plaster casting process; the metal parts/mould is casted finally.更多还原
