The method of layer-by-layer build-up of the material allows creating parts of complex configuration.To expand the field of application of such parts in the industry, it is necessary to know the properties of products obtained by this wayvery well. Currently, the literature sources do not provide enough information about the properties of products obtained by 3D printing on FDM-technologies.This is due to the variety of materials used and printing modes.Data on mechanical properties, such as tensile strength, bending, compression, shrinkage, specific weight of the material, will allow designing and creating real structures using 3D printing.The article considers the extrusion method of 3D printing, describes the study of tension, compression, bending, specific weight, shrinkage of samples with different structures obtained from ABS plastic.It is found that the deformation of the material during its tension depends on the number of filaments on the shell of the surface layer and reaches the highest values for samples containing eight and ten filaments. The calculation of the specific weight of the samples shows that the density of the samples with a tetrahedral structure is higher compared to the hexahedral structure at the same printing and filling modes. In determining the ultimate compressive strength of the samples, it is revealed: the higher the percentage of sample filling material, the more the sample withstands compressive stress. Experimental data on material shrinkage show that when filling the model with material from 20 to 80% shrinkage is 1%, and at 100% filling - 0.78%.

Wide integration of computing resources into physical processes resulted into evaluation of new concepts and evaluation of a concept of cyber-physical sysems in particular. The article reveals an approach of implementation of cyber-physical processes into construction field. Since the process of construction faces the problems, which were traditionally considered as poorly formalized, that leads to an accumulation and transfer of huge amounts of often heterogeneous in its structure and purpose of information. As a result of a detailed analysis of the prerequisites for the creation, structure and functions of cyber-physical systems, the authors establish that the solution of such problems is engaged in cyber-physical systems.
