Abstract
One of the main advantages of additive manufacturing is the possibility of custom-made machine parts. Additive manufacturing enables the production of components with fine details that would be difficult to manufacture with conventional production. This, however, brings some difficulty in the case of the acquisition of conventional test specimens that might exceed the size of the product. Mechanical properties of the tested materials via standard and micro-tensile test specimens were analysed. The materials AlSi10Mg and MS1 in as-built (AB) and heat treated (HT) conditions were produced by laser powder bed fusion. The aim of the research is to observe the influence of parameters (sample size, direction of testing) on the resulting mechanical properties. Mechanical testing is supported by metallographic and fractographic analysis.
