This study aims to analyze the design rules in making a specimen or object based on position orientation to know the effect of build orientation. The direction of the position used consists of seven variations of angles, including 0°, 15°, 30°, 45°, 60°, 75°, and 90°. All variations are fabricated using the FDM Creality Ender 5 machine and then tested in the form of a tensile test. The greatest strength of the specimen is the 90° in orientation position with a value of 30.6 MPa. In comparison, the most negligible strength is the 0° in orientation position with a 7.5 MPa. This analysis is related to the parameters that affect the printing results, such as orientation of the print position, quality of the material, printing temperature, and size of each layer. © 2024 Author(s).
