Renfe has decided to turn to 3D printing to produce components on demand using Aragonese technology. Specifically, one that provides Aitiip Technology CenterA reference at a national and European level has signed a two-year agreement to work hand in hand in a manufacturing process that saves costs and delivery times in the maintenance of its trains.
The company consolidates in its industrial area Advanced Detailed Additive Manufacturing Service (3D Printing) forSupplying railway components, thus meeting the requirements Manufactures parts for your trainIt may be a new product or a replacement for obsolete or damaged ones that need to be replaced.
To do this, you have already created 3D Printing and Reverse Engineering Pilot Center It consists of a team of Renfe engineers and Aitiip specialist staff in the facilities of the Villaverde comprehensive maintenance site in Madrid, who create a database of parts that can be manufactured this way. First, identify what they are about The pieces that can be produced with this technology, their digitization and creation of an inventory It can be used from any maintenance site throughout Spain.
Across Spain from Zaragoza
Production from Aitiip's facilities in Zaragoza will be distributed nationwide on demand. What is the benefit? “Delivery times are much shorter as a piece that they now receive in four months will now be received in 15 days at most.And maybe now because the costs are going down a lot For around 20 euros you can now get 4,000 paid items„, David Roba, head of engineering at Aitiip, explained to EL PERIÓDICO DE ARAGÓN.
It should be taken into account that „trains have a very long useful life, which can reach 40 years, and It may be that the original manufacturer does not exist or that parts that need to be urgently replaced are manufactured.. When they need a replacement, it is very important to have it in 15 days and as reliable as the original.” At this time, the „library” of Renfe components was already created with a good number of components. , all related to the maintenance and „nothing to safety” of those trains, and ” Work is underway with a view to increase this in the coming years.
Renfe and Aitiip will combine skills and knowledge with the team responsible for coordinating and developing the work. From Villaverde to provide support to all the maintenance centers that Renfe has throughout Spain. In this way, the company gains freedom when meeting those production needs Supply of spare parts is not essential to the safety of your fleet. You can make other improvised or tooled materials, tools and equipment useful in other production and maintenance tasks. Aitiip's contract with Renfe starts in early 2023.
Ventilation grills or engine covers
This service is all inclusive Product value chain, from identifying and analyzing each requirement, to scanning part geometry or 3D digital modeling. One technique allows pieces to be reshaped (enhanced) and then printed Plastic products In addition to materials such as high mechanical performance and certified for railway use under fire and smoke regulations Aluminum oh Steel And training is provided to Aitiip's technical teams.
Renfe and Aitiip teams are working on design and production Fragments andReinforced tools For use in different manufacturing processes, or Parts Prototyping For subsequent production using traditional technologies. Among other elements, several series of fragments such as cavities Driver's cabins or Regulates caps Injection pump of Convoy diesel engine.
All the information gathered from the fragment becomes a part 3D Digital Inventory, into the stage AD 2 of Advance 3D, One of the successful startups of the III TrenLab call, Renfe's open innovation project.A tool developed within the framework of the service, and supports accurate tracking of each part's data (material type, dimensions, markings, cost) with the aim of improving production time in case of future requirements.
