THE TECHNICAL AND ECONOMIC ASPECTS OF IMPLEMENTING INNOVATIVE 3D PRINTING TECHNOLOGIES IN CONSTRUCTION

Abstract. The article is dedicated to analyzing the evolution of additive technologies from their inception to the present state. Special attention is given to the development of 3D printing technologies in construction. The research covers the historical context of the emergence of additive technologies, an analysis of current trends, and prospects for further development. Examples of successful applications of innovative 3D printing technologies are provided, and the main advantages and challenges associated with their implementation in construction are identified. An analysis of the additive technologies market in construction is conducted, revealing a positive trend toward further growth across all types of additive technologies, driven by their innovative potential, increasing demand, and integration into the manufacturing processes of various industries across countries. The article proposes the main directions for the further development and implementation of additive technologies in the construction sector. Key factors that will stimulate the development of the 3D printing market, such as the need for continuous improvement of hardware and materials, the reduction in the cost and availability of 3D printers (which will encourage their adoption by small enterprises), and the diversification of the 3D printing technology’s application areas based on user needs, are highlighted. A correlation between the development of the 3D printing market and other industrial sectors is identified. A comparative analysis of capital investments using traditional construction methods versus 3D printing technology across countries confirms the conclusions regarding the increased efficiency and cost reduction of projects through additive technologies, which is particularly relevant in the context of rebuilding Ukraine's damaged infrastructure. The prospects for the development of 3D printing technology in the construction industry, both in Ukraine and globally, are examined. A promising additive technology in construction, known as robocasting or direct ink printing, is studied. This technology serves as an alternative for manufacturing products with complex geometries that are practically impossible to create using traditional construction methods. Based on the conducted research, recommendations are formulated for creating favorable conditions for the development of additive technologies in Ukraine through the development of regulatory frameworks, technology accessibility, and the need for skilled workforce training.
