Analysis of the design of 3d printers for layer by layer concrete pouring

Abstract

In this work, the technology of layer-by-layer concrete pouring and construction of 3D printers was studied. The degree of freedom of the working body of a 3D printer in the design, which allows the print head to move along a given trajectory, directly affects the pouring of layered concrete from a simple parallel shape to a complex shape relative to the ground. The designs of 3D printers in construction are analyzed in detail, the features of each design are considered, their advantages and disadvantages are analyzed. Almost all of the considered designs of 3D printers are taken from real projects. In addition, the dimensions and features of work areas that can be provided by construction 3D printers during construction are discussed, as well as their direct impact on the shape, complexity and size of the building under construction.
