Additive Manufacturing in Hydraulics

 

Aidro introduces the additive manufacturing in the hydraulic sector, beside the traditional manufacturing.

 

 

This new technology can produce hydraulic components starting with loose material, powder metals, and then builds it into a 3-dimensional shape using a digital template.

 

 

On the basis of 35 years of experience in hydraulics, Aidro considers the additive manufacturing a good alternative to the traditional subtractive  production in case of specific customer requirements, such as high degree of customization, complex geometries and low production volume.

 

With additive manufacturing, Aidro wants to exploit the potential offered by 3D printing such as short lead time, flexibility of forms, variety of materials, rapid prototyping and multiple models, just to list a few of the key benefits.

 

 

 

At Aidro, we love the idea of creating the impossible thing and we see ourselves as pioneers in the introduction of additive manufacturing in the hydraulic sector”, said Alberto Tacconelli, Managing Director.

 

 

 

We believe in additive manufacturing :

                            The future of making things!

Traditional manufacturing versus Additive manufacturing

HYDRAULIC VALVE BLOCK

Hydraulic manifold 3D printed

This is a 3D hydraulic valve block printed in stainless steel for controlling a single-acting cylinder.

 

The traditional hydraulic block has been redesigned with a different and innovative design approach: put the valves in which it is necessary and connect the valves, as you wish, with the main objective to reduce the mass of the component whilst retaining its robustness.

 

Additive manufacturing is highly suited for the design and manufacture of manifolds due to its ability to build internal features and passageways. Our internal channels of the valve block are optimized to a better flow and space savings, while the potential for leakage is removed because auxiliary drillings are no longer necessary.

 

This 3D printed hydraulic block greatly meets the specific

needs of customer.

 

 

 

3D printing advantages:

 

  • Freedom to design
  • Possibility to produce complex geometries
  • High customization
  • Space saving

PRESSURE REDUCING VALVE BODY

In order to have a lightweight hydraulic valve, this stackable valve body has been redesigned to be 3D printed.

 

The additive manufacturing allows a high reduction of the material used for the production, and the final weight of this valve has been reduced by 60% less.

 

With the addition of the pressure-reduction cartridge, we have created a direct operated pressure reducing valve in stainless steel. While, normally, the standard pressure reducing valves are made in steel zinc plated. Moreover, during the pressure tests, the 3D printed valve has demonstrated the same results as the

traditional manufactured valves.

 

To test the materials variety offered by additive manufacturing, this hydraulic valve has been 3D printed in stainless steel, aluminum and in Maraging steel. The first material offers an high corrosion resistance, and it is widely used for special applications, such as oil&gas, yacht and naval. Aluminum is lightweight and Maraging steel is known for possessing superior strength and toughness

without losing malleability.

 

 

 

 

3D printing advantages:

 

  • Weight reduction
  • Possible choice between high performing materials
  • Optimized performances

HYDRAULIC SPOOL

This spool has been redesigned in order to be 3D printed with new holes forms, such as oval holes and square holes.

 

These shapes are impractical with traditional manufacturing, in particularly with CNC machining, while with additive manufacturing complex geometries are now feasible.

 

Indeed, with the new holes forms, our idea is to increase the passing area of oil inside the spool, allowing lower pressure drop. Therefore, the new design with additive manufacturing offers an higher performance.

 

Moreover, with the ability to build complex geometries, we have consolidated more components into one piece and our 3D printed spool is one single part. This allows to simplify the manufacturing process and reduce assembly time.

  • Availability of geometric forms impossible with traditional machine
  • Ability to combine multiple parts into one
  • Possible better performance than the traditional manufacturing
