Abstract
This paper presents results on processing AZ31 magnesium alloy with Selective Laser Melting technology. The process optimization was performed according to the Design of Experiments methods. The porosity analysis shown that fully dense specimens were achieved. Thanks to the Analysis of Variance (ANOVA), the impact of changed parameters on the porosity was characterized. The paper also presents results of material characterisation. Microstructure evaluation shown fine, equiaxial grains, which could be responsible for uniform mechanical properties and good elongation. Carried out mechanical tests proves, that the properties of AZ31 material obtained in additive process are correspond for conventional cast alloy.
