3D printing is a method of stacking materials in layers, enabling the production of sophisticated and complex products at a lower cost while consuming a smaller amount of time compared to cutting methods such as those that employ conventional machine tools. The development of 3D printers has suggested a new paradigm for production and manufacturing methods; however, the method and criteria for structural diagnosis for additive manufacturing are unclear. In this study, a test piece for the evaluation of ultrasonic propagation characteristics according to the lamination thickness and lamination conditions was fabricated with ABS resin using the stereolithography apparatus (SLA) method. Based on this, a defect specimen was prepared with additional defects of different sizes; non-destructive evaluation of the 3D printer output was performed using an ultrasonic technique, and its correlation with the stacking conditions was studied. It was confirmed that the ultrasonic propagation time rapidly changes up to a stacking thickness of 1 to 4 mm, and it can be seen that the ultrasonic propagation speed converges to an error range in the region where stacking thickness exceeds 6 mm. Based on these results, it will be possible to expand the application of 3D printing to industrial sites by securing the state and reliability of the laminated product.
