  • Key stakeholder to work together to define requirements and standards for 3D Metal Printing

    The Northern Italy-based Aidro Hydraulics & 3D Printing welcomed a 2-days meeting of the Joint Innovation Programs (JIPs) focused on Additive Manufacturing of functional production parts for the Oil, Gas & Maritime industries. Participating companies in the project include key stakeholders such as Equinor, BP, Total, Rolls Royce Marine, TechnipFMC, Vallourec and other companies specialized in additive manufacturing such as Aidro, SLM Solutions, Additive Industries, Voestalpine, OCAS, Ivaldi Group, Quintus, HIPtec, University of Strathclyde and Siemens. In fact, also in Oil & Gas it is recognized that the adoption of additive manufacturing can generate advantages in various areas such as just-in-time delivery of spare parts and reduction of stock, fast prototyping, accelerating R&D and innovative solutions. 


    The partners of the program aim to define clear requirements for parts manufactured by additive manufacturing thanks to the sharing of information and knowledge among the group. The work tools are two JIPs: one focused on defining the guidelines managed by the DNV GL and the other JIP, managed by Berenschot, aimed at identifying key pieces or case studies and following the production process through the additive manufacturing, identifying the necessary tests and making the analysis on printed parts.

    The Programs were launched early 2018 and by this year the group has grown to 17 companies, with the latest entry of Shell. Partners have periodical discussions and the preliminary results of guideline have been presented during the meeting held on March 4th and 5th at Aidro offices, near the beautiful landscape of Lake Maggiore. Between a discussion and the other, the Aidro staff organized a special visit for the partners within the company. Divided into three groups, the members were able to attend an in-depth presentation on the design for additive manufacturing. In particular Alberto Tacconelli, Managing Director of Aidro, showed the benefits that can be achieved with a new design approach and the better performances of 3D printed components. The visit continued with a tour to the AM department where metal 3D printers were at work. Finally, an active workshop has seen the visitors grapple with the post-processing and some people armed with hammer and chisel have been able to test with their own hands the complexity of the operations of finishing and supports removal.

    Aidro contributes to the JIPs with its technical expertises as a valves manufacturer in conventional way (this was the main activity for almost 40 years) and as user of metal additive manufacturing. Aidro has discovered 3D metal printing a few years ago and now, thanks to the  enthusiasm of its CEO, Valeria Tirelli, the company has an internal department dedicated to the design and production with laser powder bed fusion 3D printers. Thanks to the technical knowledge of the valves sector, manifolds and hydraulic components in general, and to the experience with the new additive technology, Aidro's contribution is considered very important within the JIP. Indeed, the goal of the JIPs they collaborate in,  is to develop a guideline and accompanying economic model to print qualified, functional metal production parts, to be used in the Oil, Gas and Maritime industries. So the experience in the field and in the daily work with additive technology, allows Aidro to be taken as a model to be compared with the requirements of the guidelines.

  • Complex hydraulic components made via metal 3D printing can incorporate details that would be difficult or impossible to duplicate through conventional machining, and weight and size are reduced without compromising performance.

    Aidro Hydraulics& 3D Printing uses metal 3D printing to offer new opportunities to capitalize on the high power density of hydraulic technology by improving the design and production of components such as manifolds, valve blocks, and systems.

    Without the limitations of conventional machining, parts can be designed for the most efficient combination of production and performance. And internal channels can be optimized for higher flow and lower pressure drop. It’s also possible to produce high pressure manifold with lightweight design.

    That’s the case of a portable hydraulic power unit for high-pressure. Aidro designers wanted to make the power unit as light as possible, but it seemed as if everything had been done. Integrated hydraulic circuits using cartridge valves were specified in lieu of line-mounted valves, the number of components was reduced to a minimum, and fluid lines were made as short as possible. Then designers decided to use the latest capabilities of metal 3D printing. The hydraulic manifold has been redesign using metal 3D printing and it is smaller and, especially, lighter than equivalent components made by conventional methods. 

    At left is a manifold that had been used in a portable power unit, and at right is the 3D-printed version, which weighs 75% less

    According to Alberto Tacconelli, Managing Director at Aidro Hydraulics & 3D Printing, Taino, Italy, the most appropriate type of metal 3D printing for hydraulic components, at the moment, is laser powder bed fusion (LPBF or SLM).

  • Aidro, a north Italian hydraulic systems specialist, presents metal 3D printing or Additive Manufacturing as a new technology for the customized solutions both in hydraulics and Oil & Gas applications. 

    Beside its traditional production of hydraulic component and blocks for almost 40 years, a few years ago Aidro has introduced Additive Manufacturing to produce innovative valves, manifolds and heat exchangers to take advantage of the benefits of 3D printing, such as lightweight, space saving, complex forms. Moreover, with its expertise in Additive Manufacturing, Aidro can design and develop new projects for customized requirements.

    In the photo, a comparison between the traditional Aidro manifold for mobile application and a redesigned version produced with a metal 3D printer machine. This manifold has exactly the same function as his predecessor : it controls a doubled acting cylinder with two solenoids valves and two pilot operated check valves. The complete new solution reached a 75% weight reduction and half size dimensions compared to the traditional manifold.

    The main advantages of Additive Manufacturing are the followings:  

    • compactness and fitting with smaller space available
    • lightweight 
    • reduce the number of assembling parts
    • optimize the performance thanks to curved connecting channels and elimination of 90°degrees intersection angles
    • eliminate the leakage from auxiliary drilling and plugging that normally are required in traditional manufacturing
    • more complex shapes at no extra cost
    • Rapid Prototyping
