AI中文摘要：
增材制造（AM）是通过逐层沉积材料以获得所需零件的过程。通过增材制造生产的零件因此可以采用传统制造方法无法实现的几何形状，例如中空或晶格结构，这些结构在保持甚至改善其机械性能的同时显著减轻重量。在众多现有工艺中，线弧增材制造（WAAM）特别适用于制造大型金属零件。其特点是热量以电弧形式（由焊接发电机产生）供应，材料以丝材形式供应。本文讨论增材制造对提升高价值部件性能的影响，基于海军应用：在实验室中制造了一个1.5米高的中空螺旋桨叶片演示件。
英文摘要：
Additive Manufacturing (AM), consists of depositing material in successive layers to obtain the desired part. The parts produced by AM can thus adopt geometries inaccessible by conventional manufacturing means, for example hollow or lattice structures which considerably reduce their weight while keeping or even improving their mechanical properties. Among the many existing processes, Wire Arc Additive Manufacturing (WAAM) is particularly well suited to the manufacture of large metallic parts. It is characterized by a supply of heat in the form of an electric arc (produced by a welding generator) and a supply of material in the form of wire. This paper will discuss the impact of additive manufacturing to enhance the performances of high value components, based on naval application: the manufacturing of a hollow propeller blade demonstrator of 1.5 m high realized in the laboratory.
