   В работе исследованы физико-механические свойства образцов из акрилонитрил-стирол-акрилата (АСА), изготовленных методом аддитивного производства. Изучено влияние степени заполнения (30 %, 60 %, 80 % и 100 %) на твердость, плотность и механические свойства. Установлено, что твердость по Шору Д остается постоянной при степени заполнения от 30 до 80 %, а при заполнении на 100 % увеличивается примерно на 8 %. Плотность деталей монотонно возрастает с увеличением степени заполнения, достигая максимума при 100 % заполнении. Испытания на трехточечный изгиб показали наибольшие значения прочности и модуля упругости при степени заполнения 100 %. Прочность при растяжении образцов с малым сечением значительно повышается при заполнении от 80 % до 100 % (примерно на 43 % и 76 %), тогда как для образцов с большим сечением данный параметр практически не зависит от степени заполнения. Удлинение образцов увеличивается с ростом заполнения, достигая максимума при 100 % заполнении. Результаты показывают, что степень заполнения и геометрия образцов оказывают существенное влияние на механические свойства, что позволяет оптимизировать параметры 3D-печати для создания изделий с заданными характеристиками.

   The physical and mechanical properties of acrylonitrile-styrene-acrylate (ASA) samples made by additive manufacturing have been investigated in this work. The influence of the filling degree (30 %, 60 %, 80 % and 100 %) on hardness, density and mechanical properties has been studied. It was found that the Shore D hardness remains constant at the degree of fi lling from 30 % to 80 and increases by about 8 % at 100 % filling. The density of parts increases monotonically with increasing degree of filling, reaching a maximum at 100 % filling. Three-point bending tests showed the highest values of strength and modulus of elasticity at 100 % fill. The tensile strength of specimens with small cross-section increases significantly at 80 % to 100 % filling (by about 43 % and 76 %), whereas for specimens with large cross-section this parameter is practically independent of the filling degree. The elongation of the specimens increases with increasing filling, reaching a maximum at 100 % filling. The results show that the degree of filling and specimen geometry have a signifi cant effect on mechanical properties, which allows us to optimize 3D printing parameters to create products with specified characteristics.
