## 2 Materials and Methods  
Gradually, a need for unification of the rules for the shape of test samples has emerged on the global market. In Central Europe, emphasis is placed on ISO (International Organization for Standardization) standards, where the Slovak Technical Standards (abbreviated STS) often adopt these standards either simply by translating them or through amendments, if other factors need to be accounted for. In the United States, AM (American Society for Testing and Materials) is preferred. Although standards for testing plastics have been set for a long time, the need to supplement these standards has acutely increased in recent years. An example is insufficiently defined parameters in additive production, especially for 3D printers working with metals, plastic polymers, and composites. Production of products based on additive technologies is gaining in importance, mainly due to the new production possibilities of 3D printers compared to conventional technologies. The components must be produced with the specified parameters and in the required quality. Material research of the working media and research in the field of machine design plays an important role in shortening the production time of 3D production equipment. As advances in these technologies increase, so does the need for standardization. Thanks to projects such as RepRap, 3D printers, especially of the FDM type, have been able to make the transition from top research centers to ordinary households. Thus, it is possible to produce products of the required industrial quality even at home. Within the concept of Industry 4.0, the technology is important in terms of new standards and from the point of view of the authors of this paper, it appears to be one of the possible cornerstones of the 5 th Industrial Revolution, decentralized urban-domestic production. For the formation of layered plastic bodies, the selected tensile sample to be torn may be produced with some of its parts less resilient if its production parameters were selected inappropriately. Based on similar research raster orientation play a crucial role in the mechanical performance of printed sample [42]. To achieve optimal results for all manufactured bodies, the account was taken not only of optimally setting the basic production parameters, such as the temperature and the moving speed (listed in Table 1) but also of guaranteeing dimensional accuracy and production repeatability. The G-codewas created in Simplify3D with a postprocessor profile for Creality CR-10s Pro V2 on which the samples were produced. To guarantee a constant height of the body and to prevent failures, three base layers (Raft) were formed under the body. A thinner Raft Baselayer and two Raft Top ones, on which the resulting body was subsequently printed. This prevented possible defects associated with desk wear, incorrect calibration, and imperfect printing adhesion. The heating bed was turned on throughout the whole manufacturing process. These are basic settings for production from PLA filament with small modifications. The available standards point to the principles of operation of the respective additive technology and the shape of the test specimens. However, they do not address the parameters for creating paths for the production machine, the sequence of individual production steps. The EN ISO 17296 standard Additive production-basic principles consist of the following parts:  
* Part 1: Terminology
* Part 2: Overview of processes and raw material categories
* Part 3: Main characteristics and the corresponding methods of testing
* Part 4: Overview of data processing  
Chapter 4.3 of the ISO 17296-3--Performance criteria and qualitative characteristics, the standard refers to ISO/ASTM [43] with respect to the specificity of additive production and its anisotropy--the direction in which the load is applied to the sample during the test with respect to the layering of the material fiber during the production process.
