摘要：

The direct metal lamination is a kind of the additive manufacturing process using the arc welding technology; where the molten metal made by the arc discharge is accumulated successively in this process. Overhanging shapes can be fabricated without support materials but lamination height error is caused in largely inclined area. In this paper, the lamination height error was estimated by using the accumulated metal shape model. Then, the lamination height error was compensated by changing welding torch feed speed so that the top surface of the laminated layer became horizontal. As a result, not only the lamination height error was decreased by 50%, but average inclination angle error was decreased by 50%.
