The tensile strength of parts obtained by Cube 3D printing is described in this paper. The material of the parts are PLA. In the research through the statistical analysis of results we checked whether the tensile strength of standard test specimens made by this method is equal to the tensile strength of the material. Experimental research has consisted of making parts of PLA plastics and testing the tensile strength of standard specimens obtained by Cube 3D printing process. Cube 3D process allows to easily and quickly obtain the prototype directly from 3D CAD models. Besides a number of advantages of this process, the research in this paper has shown that the tensile strength of parts produced by Cube 3D printing is somewhat less than the strength of the material. The reason is the way of printing that produces cross-sectional of part in which there are a very small cavities.
