3D printing technology has been with us for some time and continues to evolve. From large complex models to the simplest small models, printers are still limited in their technique, but one YouTuber decided to use his printer to print functional engines for smaller cars. One of the best printed engines are the Toyota 2RE, and the Toyota 4WD, which have achieved great beauty not only in terms of functionality but also in terms of aesthetics. The end result of the engine has reached great popularity in the world of 3D printing and the product can be compared to kinetic art. The young YouTuber has published a number of multimedia content.
