The emergence and development of additive technologies (in particular, fused deposition modeling, FDM) determine the intensification of research in this area, given that there is currently a transition from applied and artistic applications to the use of FDM in solving engineering problems. The paper analyzes the behavior of thin-walled shells obtained by FDM (tanks of various technological purposes) under internal thermobaric loading. The damage and destruction of the tanks were simulated. The mechanism of damage development was checked experimentally. It was concluded that an essential physical and mechanical characteristic is the product’s crack resistance, characterized by the stress intensity factor (SIF) and differs between the initial filament and the finished product. The SIF value depends on the existing defects and leaks in the formed body of the product. It is also determined by both the material used and the printing modes. It is shown that applying thin sealing films and various printing techniques can improve the mechanical characteristics of the product as a whole.
