The paper reported the results of a study concerned with the principle of operation of the 3D printing technology using the method of selective sintering of metallic powders, and taking into account their advantages and drawbacks. The principle of the operation of 3D printing technology applying the DMLS (Direct Metal Laser Sintering) method is presented. On the basis of the performed tests, the anisotropy of the printed materials is demonstrated. The reasons responsible for this phenomenon are identified. The paper presents the results of the strength tests which indicate that the crack during the test occur in the building direction of the layers during printing. The results were compiled for two different types of specimens and two different testing machines.
