Abstract
Additive manufacturing (AM) is used in metal part forming for its innovative character but its potential for sustainability is uncertain. The energy and material consumption required for manufacturing are significant. Thus, the research question of this article is: “What are the current uses of AM that present a real potential for reducing environmental impact?”. The WAAM (Wire Arc Additive Manufacturing) process appears to be the most energy-efficient in comparison to other AM processes. A process parameters study shows that deposition rate has a substantial impact on energy consumption. This parameter represents the amount of material deposited in a unit of time and is directly linked to productivity. It appears that an increase of the deposition rate leads to a reduction in energy consumption. Experiments on WAAM with a high deposition rate permits to create a database of energy and material consumption. This database is then used to identify cases of parts made with WAAM that offer a significant impact reduction compared with conventional manufacturing processes.
快速成型制造（AM）因其创新性而被用于金属零件成型，但其可持续发展的潜力尚不确定。制造过程中需要消耗大量能源和材料。因此，本文的研究问题是"目前有哪些 AM 用途具有减少环境影响的真正潜力？与其他 AM 工艺相比，WAAM（线弧快速成型）工艺似乎是最节能的。工艺参数研究表明，沉积率对能耗有很大影响。该参数表示单位时间内沉积的材料量，与生产率直接相关。提高沉积率似乎可以降低能耗。通过在高沉积率的 WAAM 上进行实验，可以建立一个能源和材料消耗数据库。然后，利用该数据库确定采用 WAAM 制造的零件的情况，与传统制造工艺相比，WAAM 可显著减少影响。
