Wankel rotary engine in 3d printing

In recent years, 3D printing (Additive Manufacturing) has evolved substantially and very rapidly, which has resulted in high affordability for the purchase of 3D printers and diversified printing by professionals, hobbyists, or the curious. Consequently, this type of technology is in a continuous evolution beneficial to mankind and offers development opportunities for almost every field existing in our lives such as: automotive engineering, space engineering, medicine, psychology, etc. The paper presents the solid modeling of the components of a Wankel engine, the method of printing the components with the help of the 3D printer, at a reduced scale compared to the real one, followed by the realization of the engine assembly, using Inventor Student 2023.
