SUSTAIN-3D #4: Key Takeaways from the March 25 Meeting

The SUSTAIN-3D community gathered once again on March 25, 2025, at the Centrale Lille campus in Villeneuve d’Ascq to discuss the connection between “Additive Manufacturing & Sustainability.” The goal of this meeting was to demonstrate that additive manufacturing supports the industry’s decarbonization strategy, which is at the heart of the regional REV3 initiative.

An event focused on sustainability!

The event featured a number of very interesting presentations on a variety of topics and examples related to the day’s theme:

EuraMaterials: Presentation and Launch of the New Online Community, Hosted on the Rés’Hauts-de-France Business. This space aims to foster discussion, share news, and facilitate collaboration around SUSTAIN-3D themes. Anyone can contribute, ask questions, publish resources, or find partners.

Sirris: presentation of innovative processes for 3D printing using rare earth metals andrecycled aluminum, paving the way for new industrial applications. These solutions aim to reduce environmental impact while maintaining high technical performance, particularly in the electronics, aerospace, and automotive sectors.

Decathlon: Introducing theAdd Lab, the group’s3D printing platform dedicated toproduct innovation, agile production, and sustainable repair. Thanks to the acquisition of a variety of 3D printers ( FDM, resin, powder sintering technologies, etc.), the Add Lab offers a wide range of solutions for rapid prototyping, small-batch production, and the reuse of parts within the after-sales service framework. The service is available to all group employees, with certain projects developed in partnership with external stakeholders.
The Add Lab also contributes its expertise in new product design, reverse engineering, and materials R&D to enhance sustainability andthe customer experience. By optimizing development cycles, reducing development costs, and promotingproduct iteration, it helps extend the lifespan of equipment distributed by Decathlon while generating a positive environmental impact.

4D Pioneers: An overview of 4D Pioneers’ approach to hybrid manufacturing through the new 4PRIME machine, a true micro-factory designed to revolutionize parts manufacturing and reduce environmental impact. The company is also focused on developing bio-based materials to support a more sustainable production model!

The event was marked by a warm and friendly atmosphere, and the discussions were followed by a tour of “LaMcube” (Laboratory of Mechanics, Multiphysics, and Multiscale) and a networking reception.
Those who were able to stay for the afternoon had the opportunity to tour the 4D Pioneers facilities.

At 4D Pioneers, participants were welcomed by Ingrid Florentin, the company’s President, and Benjamin Le Delliou, Head of the Services Department. 4D Pioneers’ services andexpertise were presented, including hybrid manufacturing technologies (notably using the 4 Prime machine) as well as the development of new materials for the rail,aerospace,energy, and maritime sectors.

Bio-based materials are at the heart of our research, and 4D Pioneers has already developed four bio-based, flame-retardant, and printable materials that comply with railway and aerospace standards: 4MELLA, 4TUNATA, 4TENEA, and 4MOSITA.

The "Services" section of 4D Pioneers has been expanded in several ways:

• Development of proof-of-concept projects
• Tips on design and material selection
• Help with setting print options
• Development of new materials incorporating recycled materials

The day concluded with lively discussions between the participants and the 4D Pioneers team. This sparked new ideas for collaborations and, we hope, new industrial projects!
A big thank you to all the speakers for their insightful presentations and their willingness to engage throughout the day!

The SUSTAIN-3D community aims tosupport manufacturers in integrating additive manufacturing into their production processes. This type of investment project is greatly facilitated when the company can benefit from the support of an entire ecosystem of specialists comprisingsolution providers, consultants, researchers,engineering schools,institutions, andcompanies that have already integrated the technology.
The SUSTAIN-3D community emerged from the convergence of two initiatives led by EuraMaterials (the Interreg SUSTAIN-3D project) and the Hauts-de-France Chamber of Commerce and Industry (3D Printing Club). The CEA and the Plastium cluster subsequently joined the initiative to co-lead and jointly develop this regional ecosystem.
By sharing knowledge on additive manufacturing, members of the SUSTAIN-3D community nurture their network and stay informed about all the latest innovations.
