Designer of a process for molding silicone parts in 3Deus Dynamics has just closed a 10 million million euros thanks to the entry into the capital of the European Bank and the European Innovation Council. These lend a hand to the Norwegian chemist Elkem, who was already present at the The first operation completed at 1.8 million in 2021, which has a silicone factory in Saint-Fons (Rhône), in the Chemical Valley.

The distribution of the capital increase is not specified, but The three founders of this spin-off of the Department of Chemistry of the of the Claude-Bernard-Lyon-1 University retain the majority. This funding also includes a grant from the EIC Accelerator and traditional bonds.

Replica of a custom-made artery

These funds are helping to develop the first 2,000 m2 factory in Rillieux-la-Pape (Rhône), where 3Deus Dynamics moved a few years ago a few months old. "We have just obtained ISO 13485 certification medical devices. We hope to mass-produce at the end of 2025 or early 2026," explains Julien Barthès, president and co-founder of the company, created in 2020, alongside Christophe Marquette and Edwin-Joffrey Courtial.

This new funding will also be used to diversify its activity. Silicone parts, ubiquitous in waterproofing by for example, are of interest to all industrial sectors. "We have focused until now on customized organ replicas, to help surgeons anticipate their operations and suppliers to better train doctors," explains Julien Barthès, whose company works with a dozen hospitals, including Lyon and Paris.

For example, before an operation on the aorta - main artery starting from the heart - the surgeons of the Lyon Sud hospital send Patient imaging at 3Deus Dynamics. In 48 to 72 hours, an artery made of silicone tailor-made with its anomaly - often an aneurysm - is available for the surgeon who will be able to better anticipate his operation.

This breakthrough innovation eliminates the metal mold step until then necessary for the development. "This shortens the time prototyping. With additive manufacturing in powders, we are able to can change the specifications several times, while the metal casting requires more time and resources," says Julien Barthès, who wants to offer this solution in Europe and the United States.

Interest of aircraft manufacturers

The company is also starting to work with clients from aerospace and defense industry for gaskets and other silicone. "Our process allows us to add functionalities. Grace to the mixture of powders, which we keep secret, we can make the piece electrically conductive, or fire or field resistant electromagnetic," he explains.

Supported by the Pulsalys accelerator in Auvergne-Rhône-Alpes, 3Deus Dynamics relies on two patents related to the 3D printing of the silicone. This industrial nugget, which employs 20 people, will Recruit for export marketing, the and then production. The business plan presented to the Investors predict 20 to 30 million euros in turnover by 2030.
