ENGIE Lab-Laborelec, Rolls-Royce Nuclear Join Additive Manufacturing.

Collaboration between Lloyd’s Register and TWI aims to bring independent certification to printed parts

Lloyd’s Register (LR) and TWI are pleased to announce that ENGIE Lab-Laborelec and Rolls-Royce Nuclear have formally joined a joint industry project to advance laser metallic additive manufacturing (AM) through the independent certification of AM-produced components. The project will continue to develop Rolls-Royce’s and ENGIE Lab-Laborelec’s understanding and certification of additive manufacturing for non-aerospace applications.

TWI will assist in optimizing the companies’ designs for additive manufacturing and in the printing of the component, while LR will bring its knowledge of product certification to every stage of the manufacturing process. The end result for both companies will be a component that is produced through additive manufacturing by TWI and is certified by LR for quality, safety and consistency.

“This joint industry project is a unique opportunity for ENGIE Lab-Laborelec to undertake required activities intended to serve for certification purposes and establish the basis for developing internal procedures which will ensure the delivery of AM components that meet industrial requirements,” said Steve Nardone, Technical Expert at ENGIE Lab-Laborelec. “The scope of this project responds to an increasing industrial demand for consistent AM product quality supported by a robust validation procedure to guarantee product compliance.”

Rolls-Royce’s Research and Technology group has been exploring AM technologies for manufacturing and repair of components for nearly a decade. ENGIE Lab-Laborelec, which focuses on research and competence for electrical power technology, is working to establish an additive manufacturing research area. 

“ENGIE Lab-Laborelec and Rolls-Royce are at different stages of adopting additive manufacturing, and this is really an ideal situation,” said Claire Ruggiero, Innovation Director at Lloyd’s Register. “Throughout the project’s duration, Lloyd’s Register and TWI will be sharing experimentation results and best practice guidance that will enable the project members to bring functional AM-produced parts to market quickly whilst meeting stringent product integrity requirements.”

Earlier this year, LR and TWI released “Guidance Notes for Additive Manufacturing of Metallic Parts”, a framework to help manufacturers achieve certification of their part or component from Lloyd’s Register. The ENGIE Lab-Laborelec and Rolls-Royce projects will both follow this framework, and findings from the JIP are expected to help shape future revisions.

Ruggiero highlighted: “Our ability to certify and provide manufacturers with a path to market is due to our collaborative efforts with TWI, as well as our active involvement with ISO/TC261 committee, which is beginning to establish standards within the field of AM.” 

Both TWI and Lloyd’s Register are also actively involved in various national strategic panels including the UK National Strategy for AM/3D Printing and the Singapore Industrial Additive Manufacturing Research Programme Review Panel.

The JIP remains open for additional industry sponsors.
