This research was performed to study the influence of the 3D printing technique on the thermoelastic effect. Specimens were made by following Standard ASTM D 638 Type 4 for tensile properties of plastics because the method of research was a tensile test using the universal tensile test machine (UTM). In 3D printing, raster angle which was the main factor was studied as factor which can affect to thermoelastic effect; and annealing was also studied because annealing can increase crystallinity and relieve residual stress and then, these can make change on thermoelastic effect. While this research was carried out, mechanical properties simultaneously were measured and it is utilized when fractography was performed using filmed scanning electron microscope (SEM) image. The main method was by filming infrared thermography for detecting temperature change. Using these methods, influence of 3D printing technique on thermoelastic effect was researched.
