This paper propose a method for detecting defects in 3D printer outputs using a transmissive photo sensor. The transmissive photo sensor measures the transmittance of the material and is used to detect defects that may occur during the printing process. To this end, the transmissive photo sensor is integrated into the 3D printer platform, and an algorithm that processes the data obtained from the sensor in real time to judge the presence of defects was developed. The results of the experiment confirmed that the propoesd system can quickly detect a variety of defects that occur during the manufacturing process. Not only can these results play a crucial role in quality control and productivity enhancement of 3D printers, but they also have potential for application in the manufacturing industry. In the future, it is expected that the defect detection system based on the proposed method will improve the stability and efficiency fo the manufacturing process.
