Given the growth of the 3D printed parts’ utilization in various applications and the need for the efficient use of the 3D printer and materials, this paper presents the results of research on the influence of the construction plan on the compressive strengths of specimens manufactured additively by the thermoplastic extrusion of the Acrylonitrile Styrene Acrylate (ASA) filament. The mechanical performances of parts manufactured using additive technologies vary significantly depending on the process parameters used. For this reason, it is necessary to optimize the manufacturing parameters of thermoplastic extrusion. Using the Anycubic 4 Max Pro 2.0 3D printer and the variable thermoplastic extrusion parameters (Lh = 0.10 mm, 0.15 mm, 0.20 mm, and Id = 50%, 75%, 100%) 45 compression specimens of ASA were manufactured. The specimens made of ASA in the X-Z plane were tested in compression on the Barrus White universal testing machine using a speed of 10 mm/min. The results indicate that the construction orientation significantly influences the compressive strength, with specimens manufactured in the X–Z plane showing values 3.26%–29.09%, which are lower than those of the specimens manufactured under identical conditions in the X–Y plane.
