Every November, La Semaine de l'Industrie shines a light on one of France's greatest assets: its industrial expertise. Supported by the FIM (Fédération des Industries Mécaniques) and Evolis, this national initiative invites manufacturers, researchers, and engineers to open their doors, share their knowledge, and — perhaps most importantly — inspire the talent of tomorrow to choose a career in industry.
This year, Lines Manufacturing was delighted to be part of this movement. We sat down with Adrien Brunet, our Polymer & Sustainability Engineer, for a video interview that captures why large-scale additive manufacturing is not just a technology story — it is a story about materials science, environmental responsibility, and the very future of how things are made.
Adrien joined Lines Manufacturing to tackle one of the most complex challenges in our field: making large-scale polymer additive manufacturing both high-performing and genuinely sustainable. His work sits at the intersection of material formulation, process engineering, and life-cycle thinking — a combination that is increasingly rare and increasingly valuable.
In the interview, Adrien talks about what drew him to the world of industrial polymers, what a typical day at Lines looks like, and why he believes that the materials choices we make in manufacturing today will shape the environmental landscape of tomorrow.
One of the most compelling aspects of Adrien's work is the link he draws between material innovation and the circular economy. Advanced thermoplastic polymers — especially when combined with additive manufacturing — offer a path toward production systems that generate less waste, consume fewer resources, and can be designed for end-of-life recyclability from the outset.
"The exciting thing about working at Lines," Adrien explains in the video, "is that we're not just using materials — we're developing them, testing them, understanding their limits. That research directly translates into better, cleaner production outcomes for our clients." This culture of continuous improvement is central to Lines' R&D philosophy and to what makes the Eschau facility a genuinely innovative workplace.
The Semaine de l'Industrie is ultimately about attracting tomorrow's engineers, chemists, material scientists, and technicians to careers in French manufacturing. Adrien's message to them is straightforward: "If you want to work on real problems with real impact — on sustainability, on sovereignty, on the materials that will build the next generation of transportation and infrastructure — industrial deeptech is where you want to be."
At Lines, we are always looking for curious, driven people who want to push the boundaries of what additive manufacturing can do. If this interview sparks something in you, we encourage you to explore our Careers page — we'd love to hear from you.
