The potential of using 3D printing in the manufacture of mini hydraulic systems

Abstract

The work is devoted to an analytical engineering study of the practicality of using 3D printing for the manufacture of hydraulic components, in order to solve the problems associated with weight, size and complexity inherent in traditional hydraulic elements. The research aims to demonstrate the feasibility of using 3D printing to achieve simplified design and increased efficiency. The work presents samples of hydraulic elements printed on a 3D printer, which reflects the practical feasibility of this approach. A simple and practical design methodology is proposed for two key components of a typical hydraulic system, namely, a hydraulic cylinder and a directional servo-valve, which allows hydraulic actuators to be controlled using any programmable microcontroller. A distinctive feature of this approach is the emphasis on the principles of compact design, which facilitates the integration of many parts into single, multifunctional part. In addition, the use of lightweight materials in 3D printing helps reduce the overall weight of hydraulic components. The proposed method also allows the integration of various hydraulic elements into a single integral structure printed on a 3D printer, offering a pragmatic solution to the size and complexity issues associated with traditional metal hydraulic systems. The scope of this innovative approach extends to the creation of prototypes of hydraulic and pneumatic robots, as well as devices that require compactness, precision and adaptability. This methodology is promising for implementation in the field of robotics, especially for tasks where space and weight constraints are critical factors.
