The results of studying the dynamics of a construction 3D printer of manipulator type are considered. The analysis of the relevance of the 3D printing in road construction use, comparison of the technology with traditional methods of concrete structures construction is carried out. The choice of the investigated device type has been substantiated. A brief description of the construction 3D printer device, its element base and operating principle, illustrations of the research object and graphic materials are given. Forming without formwork using sliding formwork is considered, the mixture is compacted by the vibrator of the installation. A model of a construction 3D printer has been developed, which makes it possible to study the dynamic processes of interaction of the sliding formwork of the installation with a concrete mixture during construction products 3D printing. The temporal values of vibrations of the construction 3D printer trolley have been determined. The graphs of the oscillatory process of 3D printing and the time dependences of the electric current in the starting and operating modes were obtained.
