    Abstract. The results of a study of the effect of the type of lattice and the percentage of filling on the strength and deformation characteristics of 3D-printed polycarbonate under compression are presented. It is established that the most optimal filling option is the "triangle" type of lattice. The influence of the direction of compressive force relative to the orientation of the printed layers on the nature of deformation and strength properties is revealed. Due to the layered structure of the printed products, the strength characteristics of 3D-printed structures are determined by the strength of the layer itself and the contact zone of the layer surfaces, as well as the deformability of the filling grid. Based on the data obtained, the most optimal option is a compressive force perpendicular to the printed layers. The influence of temperature on the physical and mechanical properties of 3D-printed polycarbonate during stretching is also evaluated. Experimental studies have shown that with increasing temperature, the strength and rigidity of samples made using additive technologies decrease.
    Keywords: polycarbonate, additive technologies, 3D printing, compressive and tensile strength, percentage of filling, type of lattice
