直接金属层压是使用电弧焊接技术的增材制造工艺之一;其中通过电弧放电制成的熔融金属在该工艺中连续累积。在这项研究中，进行了两种不同的金属制造。一种是铝合金和钛合金。另一种是不锈钢和镍基合金。研究了异种金属结构的边界。因此，提出了用一种以上的金属材料通过直接金属层压来制造的可能性。
The direct metal lamination is one 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. In this study, two kinds of dissimilar metal fabrication were conducted. One is aluminium alloy and titanium alloy. Another is stainless steel and Ni based alloy. The boundaries of dissimilar metal structures were investigated. As a result, it is suggested the possibility of the fabrication with more than one kind of metallic material by direct metal lamination.
