3D printing is now becoming an integral part of technological development worldwide. The growing popularity of additive techniques means that more and more money is being spent on them, and their applications are gradually extending into more areas of life. Incremental manufacturing makes it possible to produce both prototypes and finished spare parts, the properties of which are comparable, and often almost identical, to components currently in use. With this technology, it is possible to create components with complex geometries without having to invest in costly, advanced mass production. 3D printing technologies make it possible to construct three-dimensional objects based on successive layers of material. Testing of the additive-printed samples was carried out using an orthogonal plan, in which factors are selected so that each is different from the others. This means that during the experiments, the influence of the individual parameters could be assessed independently, without interference from other variables. As part of the study, specimens were prepared and subjected to a static tensile test. The test models were printed with five different infill densities: 20; 40; 60; 80; and 100. After testing, the results obtained were collated in the form of graphs illustrating, among other things, the tensile strength of the Young’s modulus values and the percentage strain. These data were then analysed and described in detail for all selected materials. The highest tensile strength value was obtained for the PET-G material with 50.09 MPa at 100% infill. The lowest tensile strength value was achieved by the ASA material – 23.43 MPa at 20% infill. The highest Young’s Modulus value was achieved by the ASA material – 1924 MPa at 100% infill. The lowest value of the Young’s Modulus was obtained for the PET-G material – 934 MPa at 20% infill. The material and the infill density have no significant effect on the deformation value. The results showed that changing the infill density has an effect on the strength properties.
