Abstract The feasibility of using the Laminated Object Manufacturing (LOM) process for rapid manufacturing of the metallic functional parts with complex surface was studied in this paper. The theoretical manufacturing error and the quantity of remaining material to be removed by finish manufacturing process caused from current LOM process were analyzed, and compared with 3-D numerical control manufacturing. A new approach for cutting metallic laminating layer was presented for reducing theoretical manufacturing error and quantity of remaining materials. Case study of cylinder surface demonstrates the effects of new LOM process that it could increase the thickness of the laminating layer from 0.05-0.l mm to l.0 mm grade. Even with such thicker metallic laminating layer, we also can get similar to or lower theoretical manufacturing error and remaining material quantity than current LOM process. It may indicate that metallic functional parts with complex surface could be rapidly manufactured with new LOM process. (Auth abstract) [References: 5]
