Improvement of 3d printing object equipment

Various industries use innovative building technologies aimed at improving the quality of housing and reducing its cost, the construction of modern industrial facilities. These technologies provide for the practical use of achievements in the IT sector, which provides the latest direction in the development of building clusters and the development of startups. These technologies include 3D printing of objects for various purposes. 3D printing is the process of reproducing a real object following the model of a 3D model. The technology of 3D printing is based on the principle of layer-by-layer creation of a solid model. 3D printer allows you to display three-dimensional information, that is, to create certain physical objects. In construction, 3D printing requires the creation of technologies, materials, efficient equipment, and a regulatory framework. Purpose. The development of innovative 3D printing technology in construction to create the latest startups in this field. The results of the study. An innovative project for 3D printing of construction sites is associated with the improvement of equipment. Designed 3D printer in the form of a bridge structure with a rotary manipulator. Various types of 3D printer heads have been developed: with several extruders installed at different levels; with a movable middle extruder for laying stiffeners between the external and internal wall structures of buildings; with the ability to adjust the parameters of the layers of laid raw materials. Conclusion. Innovative construction technologies, in particular 3D printing of objects, are aimed at improving the quality of housing and reducing its cost, the construction of modern industrial buildings. This technology provides for the practical use of achievements in the IT field, which provides the latest direction in the development of building clusters and the development of startups. Various types of 3D construction printers are considered, which have drawbacks and require improvement. Promising designs of 3D printers and their components have been developed, which provide for the expansion of technological properties of equipment and increase productivity.
