The article discusses the technology of 3D printing in the field of construction in detail. The analysis of the technical constraints of the technology, as well as the architectural and planning possibilities of using 3D printing is carried out. In the course of the study, it was found that the technology is developing and expanding its opportunities: the search for new material properties, production technologies, combination of elements and extension into the typology of structures: residential and civil construction, infrastructure facilities, small architectural forms, etc. The article contains graphic examples. The study examines the modern market of 3D printing construction, as well as analyzes the prospects for using this technology in construction. It has been established that the number of structures built with 3D printing technology (in full or in part) increases annually, which generates interest not only in the development of the technology, but also in the experience of its application. The article provides conclusions which determine the potential of 3D printing as the main technology of the future in mass residential construction. It also raises the issue of developing concepts for the application of technology in order to minimize time and resource costs.

Large cities are multifaceted organisms. They are arena of social and urban conflicts. In current conditions of technological development and improvement of the urban environment quality, local authorities are increasingly reorganize industrial areas. The relevance of the article is determined by the global trend of finding new forms of renovation of depressed areas, which are explored quite well and reflected in the general vector of policy of developed countries. According to the research, it is ecological and urban forms of renovation that can ensure the efficient use of resources and create quality conditions to improve the living standard of population. The purpose of the article is to establish ecological and urban forms of renovation of industrial areas. The article substantiates the term "ecological and urban renovation", which main principle is to open new opportunities for depressed areas and buildings in order to improve the ecological and urban situation of the environment. Methods and approaches to the ecological and urban planning form of renovation of depressed areas are described. This allows adapting industrial architecture to modern urban conditions with a numerous architectural techniques. The study examines foreign experience of redevelopment of industrial territories in Barcelona (Spain), Berlin (Germany), London (UK), Paris (France), Copenhagen (Denmark). The analysis of global practice shows that the most successful examples of ecological and urban transformation of industrial areas are implemented through the principle of landscape design and methods of integrating elements of industrial heritage into public space. Consequently, by means of landscape design, the art space as a new phenomenon in the urban environment is created, which improves the aesthetic perception of the architectural city image. The experience has shown that industrial areas, which are located within the city, should be used for recreational and commercial facilities or residential real estate, whereas the areas near the city could be used for high-tech and environmentally-friendly industries.
