In parallel with the technological developments, especially manufacturing and automation, many areas are experiencing new developments in the all world. These revolutionary technological developments are mentioned with different names (4th industrial revolution, digital transformation, etc.) and new inventions are present under different disciplines. Among all these developments, the most important advancements are the field of manufacturing. In recent years, 3D printing technologies can be said to have noteworthy studies in many countries. 3D printing technologies make it easy to manufacture complex parts. Although 3D printing is a new technology, it has been rapidly spreading in many other sectors, especially in education. However, these devices have a significant disadvantage. 3D printing technologies depend on a user. After the manufactured part, the parts need to be removed from the manufacture table for a new manufacturing. This prevents 3D printing technologies from becoming a mass production tool. In this study, design and manufacturing of the continuous automatic 3D printing device based on image processing method with the conveyor system will be performed. Also, the error rate of the surface quality of the samples was determined by the image processing method. Due to the ability to print continuously without user intervention, it will be increased the capacity and the functionality of the manufacture volume of 3D printing technologies.
