Technological processes in all branches of production are maximally automated in the world, this also applies to construction. The main driver of automation of construction processes is 3D printing technology. The first driver was the invention of stereolithography technology, which was discovered in 1986 by American engineer Chuck Hull. The article describes the process of 3D printing technology, using different materials and printing principles. The main 3D printing includes the application of the material in layers at high temperatures (for small plastic products) and layer by layer of concrete mix and geopolymer concrete when printing houses. The first to start using 3D printers in construction was the Chinese company Winsun. Also considered are building structures (buildings and structures) that were built using 3D printers, compared to their technical and economic indicators. The positive and negative aspects of the use of 3D printers in construction are studied. In the future, it is planned to study plastics of ABS and PLA brands to create structural building elements with the subsequent use of these elements in construction.
