UK-based fluid power systems manufacturer Domin has collaborated with metal 3D printing specialist Renishaw to redevelop some of its products. High-performance direct drive servo valves, used for transforming signals into pressure, at the company have been made smaller, cheaper and more efficient using the technology. Renishaw’s metal powder bed fusion printer RenAM 500Q has been used to produce the redesigned rotary valve.
Fluid power systems utilize liquids or gases under pressure to generate and transmit energy. The pressurized fluid bearing performs work directly on a piston in a fluid motor. Then the fluid motor creates a torque which sets the fluid in rotary motion. To regulate the system, valves are used as control components. Compared to mechanical or electrical drives, fluid power systems are more compact, last longer and allow more precise control. Major markets for fluid power are Formula 1, space, aerospace, automotive, mobile hydraulics and industrial plants. Domin’s new direct drive servo valve in particular serves both aerospace and industrial markets.

A variety of sectors are employing additive manufacturing in high value, small volume production. For example, 3D printing software company Betatype used RenAM 500Q to make orthopedic implants. “Additive Manufacturing is a key technology for Domin,” Martin McMahon, AM Lead Technical Consultant at Renishaw commented. “It gives the company the ability to build complex parts, free of tooling and with minimal operations and assembly. Trying to integrate such complex functionality into...
