From prototyping to production: Dynamic Molding unlocks the future of silicone 3D printing

As a laureate of the I-Demo program under France 2030, 3Deus Dynamics is accelerating its disruptive vision with its patented Dynamic Molding process.

A Breakthrough in Silicone Additive Manufacturing

By replacing support structures with a granular medium that acts as a 100% reusable adaptive mold, the company unlocks an unprecedented level of freedom: printing standard injectable silicones into complex geometries with complete mechanical fidelity.

The technology first proved its efficiency in healthcare with biomimetic silicone anatomical models, used as functional organ replicas. They provide a relevant preclinical alternative to animal testing and support surgical planning, simulation, and training with unmatched anatomical and mechanical fidelity. In parallel, the integration of functional powders led to enhanced silicones with advanced properties such as electromagnetic shielding, fire resistance, conductivity, and vibration damping. The first electromagnetic shielding silicone seal, validated in flight on a helicopter, demonstrates the maturity and aerospace potential of this breakthrough.

Removing Barriers to Unlock Industrial Scalability

By successively removing the main barriers of silicone 3D printing—geometric complexity, the need for support structures, and material reformulation—the technology now opens a new frontier: scalability and productivity. Aerospace and defense industries require components over one meter in size, manufactured at industrially compatible rates. To address this challenge, 3Deus Dynamics is scaling up through multi-axis collaborative robotic 3D printing, integrated into its I-Demo project (France 2030), which received funding in September 2025.

This new generation of equipment combines the flexibility of Dynamic Molding with the precision of cooperative robotic arms, capable of executing complex toolpaths in parallel. Automation will become a major driver of synchronized management of multiple print heads, real-time deposition control, and instant adaptation to changes in material behavior. The integration of sensors and expert systems, powered by artificial intelligence and numerical simulation, enables continuous optimization of part quality and repeatability.

Toward an Intelligent, Large-Scale Production Ecosystem

This unique combination of viscoelastic processing in a granular medium, cooperative robotics, and advanced automation unlocks an unprecedented degree of freedom: large-scale printing (up to the decameter range), topological optimization, and direct functional integration into the material, while ensuring robustness and productivity. This is no longer just 3D printing, but a modular and intelligent production line, designed to move seamlessly from prototype to mid-series production.

With this trajectory, 3Deus Dynamics is preparing a true breakthrough in additive manufacturing: transforming 3D printing into a tool for material engineering and automated production, delivering tailor-made solutions for the most critical environments in healthcare and aerospace.
