PARIS, France, June 25, 2025 – Dassault Systèmes and the French designer Patrick Jouin has unveiled “Ta.Tamu” a lightweight, 3D-printed chair, co-created using the 3DEXPERIENCE platform on the cloud. Ta.Tamu is a proof of concept for generative design processes that use AI-driven virtual twins and effective material usage to support sustainable manufacturing.
Ta.Tamu is the result of a four-year collaboration combining Patrick Jouin’s design with Dassault Systèmes’ 3DEXPERIENCE platform, bringing together generative design, virtual twin technology, and sustainable manufacturing. The project team looked for new ways to design a chair, tested different shapes and structures, and found methods to use less material.
Ta.Tamu was developed through an iterative process that combined concept development with early-stage life cycle assessment. Its design draws from biomimicry and the structure of human body, such as bone density and joint articulation. The structure weighs 8.6 pounds (3.9 kg) can support 220 pounds (100 kg), and can be 3D printed in a flat, folded position without assembly.
“Nature uses only the energy and materials it needs. We wanted to apply this very simple philosophy to the development of Ta.Tamu. With the help of new collaborative technologies of Dassault Systèmes, we are now able to come up with new ideas and make them possible, creating more efficiently while producing less waste, right from the design process,” said Jouin.
Using AI-powered virtual twin, design teams modeled and simulated the behavior of complex assembled components. Topological optimization was applied to refine joints, articulations, and areas under pressure or load. Throughout the process, the design evolved within the 3DEXPERIENCE platform, with real-time updates reflected in the virtual twin. Teams adjusted the chair’s geometry while balancing its aesthetics. The final design achieves a 75% weight reduction compared to a version produced at full material density, without compromising on stability.
“To improve the world we live in, we have to change the way we produce, design and use materials. Ta.Tamu represents a call to action for industry to embrace a generative economy instead of continuing to create without limits,” said Anne Asensio, vice president design experience, Dassault Systèmes. “Ta.Tamu was created with the technology used to innovate sustainably in industrial contexts. As a science-based company, we want to create value for society in every aspect of people’s lives through our 3DEXPERIENCE platform. Design processes integrating modeling and simulation from the start lead to innovations that improve real life.”
