Research into Technologies of 3D Printing of Concrete Structures in Construction
The main purpose of the article is to analyze the adaptation of the technology of 3D printing of concrete structures. Additive technologies (3D printing) are some of the forms of additive manufacturing technologies, where a three-dimensional object is created by overlaying successive layers of material (printing, growing) according to a digital model. Printing is carried out by a special device - a 3D printer. The creation of the object takes place by sequential application of plastic material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing equipment. 3D printers offer the ability to print parts with multiple materials and different mechanical and physical properties in a single printing process. 3D printing allows you to convert models obtained in CAD systems into finished products. In real life, the 3D printing process requires preliminary preparation and post-processing of printed parts to achieve their required quality. The main types and principles of operation of 3D printers and technologies for 3D printing of concrete structures are analyzed. The design and operation of a laboratory 3D printer are analyzed.
