Abstract: When using some technology for production of final parts, it is necessary to know what parameters will be reached. If this parameters are sufficient for selected purpose. The same situation is with using of new or specific materials. It is necessary to test it formerly. It is necessary to test and figure out what is the strength of selected material. In additive manufacturing are used more technologies which works with wide spectrum of materials. Such technologies use materials in different forms, as liquid, powder or solid state. Presented paper deal withtesting of specimens which are produced on additive manufacturing device.Used device is 3D printer from the group of Fused Deposition Modeling technology (or Fused Filament Fabrication), which work with polymers filaments. Processed experiment is focused to measuring of tensile strength of produces specimens. Shape and dimensions are designed by standards. Material of produced specimens is polylactic acid (PLA), what is ecological polymer. Paper brings results about tensile strength of PLA material produced by different settings regarding prepared design of experiment.
