Three-dimensional printing techniques enable three-dimensional objects to be formed by successive layers of material, according to a previously developed numerical model. The primary aim of this study is to analyse the mechanical properties of selected materials used in the spatial printing of machine components and marine equipment. Experimental testing of samples made using the additive method was carried out using an orthogonal plan, in which the experimental factors were selected in such a way that the influence of each factor on the measurement results could be independently assessed.
This approach allowed for the elimination of mutual interference between variables and the obtaining of reliable and comparable results. As part of the research, a set of samples with five different filling levels was prepared: 20%, 40%, 60%, 80% and 100%. They were then subjected to a static tensile test to determine such strength parameters as yield strength, tensile strength, Young's modulus and relative strain. The results obtained were summarised in the form of graphs and tables, which enabled a detailed analysis of the influence ofthe internal structure and filling level on the mechanical properties of the tested materials.
