The article presents the results of comparative tests for the tensile strength, modulus of normal elasticity and water absorption tests of samples made of 3D-printed polymer materials. Polymer materials are used to manufacture hulls and superstructures of ships and vessels. In the course of the work, data were obtained on the tensile strength, relative elongation and water absorption of samples with different degrees of filling, made of ABS plastic using the FFF 3D-printing method. The modulus of normal elasticity and specific tensile strength were calculated relative to the density of the samples. Histograms of the dependence of the modulus of elasticity and specific strength on the degree of filling were compiled. Graphs of the dependence of the ultimate strength and relative elongation on the degree of filling were constructed. Histograms of the dependence of the sample mass on the holding time and a graph of the dependence of water absorption on the percentage of filling are compiled. The substantiation for the obtained results is given, conclusions are made on the possibility of using the studied polymeric materials for the manufacture of hull structures of small vessels.
