直接金属叠层是一种利用弧焊技术的添加剂制造工艺，在这个过程中，由弧光放电产生的熔融金属不断积累。悬挑形状可以在没有支撑材料的情况下制作，但在大倾斜区会造成层高误差。本文采用累积金属板形模型估算了层压高度误差。然后，通过改变焊枪进给速度来补偿叠层高度误差，使叠层的顶面变得水平。结果表明，不仅叠层高度误差减小了50%，而且平均倾角误差减小了50%。
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%.
