In this work, we investigated a series of specimens made of acrylonitrile-butadiene-styrene terpolymer using fused deposition modeling (FDM) method, currently one of the most popular additive manufacturing techniques. We used Dimension Elite BST 786 (Stratasys) 3D printer for the manufacture of specimens, while reference samples were produced by injection molding using laboratory injection molding machine Battenfeld 350 Plus. The effect of the plastic layer thickness and orientation of the model in the device workspace on the mechanical properties and dimensional stability of the products was studied. For this purpose, three different specimen orientation angles with respect to Y axis: 0° (flat), 45° (hemispheric) and 90° (lateral) and two layer thicknesses: 0.254 mm and 0.178 mm were assumed. It was found that the properties of the specimens produced by FDM method are generally less advantageous than those of injection-molded samples. The best specimen properties were obtained using the higher layer thickness and orientation angle of 90°.
