The use of thin-walled constructions with honeycomb structure manufactured using additive technologies has several advantages compared to the constructions manufactured using traditional technologies. First of all, this is explained by the fact that

Introduction. Benign female paraurethral masses (BFPM) are not often found during practice. This is due to the small size of the BMP and the low specificity and effectiveness of imaging techniques (urethrocystography, ultrasound, computed tomography)

FDM 3D printed honeycombs are investigated. A honeycomb is composed of regular hexagonal cells. A honeycomb is 3D printed so that the fused filament runs along the walls of its cells. We emphasize that the thickness of these walls is one or two times
