The manufacture of dimensional parts on 3D printers with a small working area for printing leads to the need to separate the model into parts, print them separately and join them after the end of printing. The paper considers various ways of joining plastic products obtained by 3D printing methods. Samples were made, parts of which were connected in the process of research in the three considered ways. The tests were carried out in accordance with the requirements of GOST 11262-2014 “Plastics. Tensile tests”. The evaluation of the deformation and strength characteristics of the joints at different temperatures (+ 20°C, −30°C, −50°C) was carried out. It has been established that negative temperatures do not have a negative effect on the deformation and strength characteristics of the joints of parts made of ABS plastic. The results of tensile tests are presented. The use of the technology proposed by the author for joining plastic parts at enterprises engaged in the manufacture and repair of dimensional products will allow expanding the range of products without significant changes in the material and technical base.
