ABSTRACT
The present work discusses the possibility of wire arc additive manufacturing (WAAM) of pure aluminum specimens (Al99.7). The manufactured specimen’s structure was studied using X-ray diffraction (XRD) experiments. The morphology of the specimen at different stages of build-up was studied by examining pre-pared micrograph samples using an optical microscope. The resultant structure has a direct influence on the mechanical properties of the specimen, and for this reason the microhardness of the specimen was studied a well. The results of the present study were discussed regarding the change of the structure of the samples with the increase of the specimens’ height during the manufacturing process and its’ influence on the resultant microhardness.
