Becoming a reference in a niche market
Very High Cycle Fatigue (VHCF) is a niche market where very few players are capable of meeting the extreme requirements of industrial companies and researchers. At 3R, we have made the clear choice to invest our expertise to become a reference in this cutting-edge sector.
It is with this ambition that we have joined forces withE-PIEZO, a French start-up from CNRS, recognized for its excellence in ultrasonic engineering. A player in pure scientific innovation, E-PIEZO shares with us the commitment to advance testing methods and provide solutions to industries inventing the materials of the future.
3R x E-PIEZO partnership: two complementary areas of expertise

The 3R x E-PIEZO partnership was born from a shared commitment to provide the most demanding sectors – space, nuclear, aerospace, energy – with solutions capable of characterizing materials under extreme conditions.
3R, for the design and commercialization of VHCF machines
E-PIEZO, which operates at several levels:
- Outsourced testing services to validate the durability and resistance of materials.
- Development of ultrasonic technological building blocks integrated into VHCF machines produced by 3R.
-
By combining the industrial robustness of 3R and the DeepTech agility of E-PIEZO, we are paving the way for a new generation of durability tests.
The benefits for you
- De-risk your innovations: validate your material and process choices through testing services, before investing in a complete system. This step enables you to secure your decisions and optimize your budgets.
- Reduce your lead times to a minimum: access fast and reliable validations for your R&D and industrial projects.
- Gain independence: start with our services, then move towards acquiring a complete VHCF machine.
- Access unique expertise in Europe: benefit from both the industrial robustness of 3R and the DeepTech innovation of E-PIEZO.
