EN The growing popularity of the Fused Deposition Modeling method in the industry and among individual users motivates to constantly research its potential. In particular, the influence of the moisture of the material on the result of the process has not yet been sufficiently described. The article presents a test that allows to determine this effect in an experiment requiring a relatively small number of repetitions. As a case study, a test for identifying the effects of material temperature, ply thickness, extrusion rate and material flow on dimensional accuracy, tensile strength and surface quality was presented. As a result of the conducted research, the possibility of using the method with a constant change of factors in the development of parameters of additive manufacturing was confirmed. In the tests performed, a significant increase in the dimensions of the produced samples was also noted with the filament moisture content at the level of 0.74%. For the given humidity, a significant deterioration of the visual condition of the surface was also noted. The moisture of material does not significantly affect the mechanical strength of the samples.
