Optimization of 3d-printing of bronze by wire-arc additive manufacturing

Abstract

The impact of heat input and scanning strategy during the printing of CuAl9Mn2 bronze by wire-arc additive technology on the structure, geometric parameters, and properties of the resulting products is examined. It is demonstrated that a higher rate of layer deposition results in enhanced mechanical properties of the material and smaller wall width and layer height. This enables the geometric parameters of the formed samples to be adjusted during printing. The deposition strategy also has a significant impact on the geometry of the products with round or rectangular cross-sections.
