LABORATORY UNIT FOR RESEARCH OF ADDITIVE CONSTRUCTION TECHNOLOGIES Russian patent published in 2022 - IPC E04G21/16 B29C64/209 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to laboratory installations, and can be used for research and testing of additive construction technologies in laboratory conditions, including properties of construction mixtures, individual characteristics and properties of building structures and elements of working equipment used for erection of structures, buildings and structures by 3D printing. Technical result is achieved by the fact that the laboratory installation for the study of additive construction technologies includes a working printing element in the form of an extruder, support frame, on which vertical guides are fixed to provide vertical movement along them of working printing element, fixed in required height position by means of retainers, and wheels, providing the plant translational movement along the X axis along the horizontal guides along the working zone, within the construction mixture layer-by-layer laying into the vertical wall, wherein laboratory unit comprises servo motors with NC connected to computer to ensure translational motion of printing tool along axes X and Z, as well as rotary motion of extruder screw.

EFFECT: determination of optimum parameters of additive construction technologies.
