On Could 2, the deeptech based in 2020 introduced that it had finalized a fundraising of 10 million euros from Elkem Silicone and the EIC Accelerator program of the European Innovation Council. Funding which can permit it to launch its first manufacturing line in early 2025 in its new 2,000 m2 manufacturing facility primarily based in Rilleux-la-Pape, within the metropolis of Lyon (Rhône), into which the corporate moved in Could 2023. But additionally to speed up its worldwide industrial growth and broaden the vary of supplies utilized in dynamic molding.
All of it begins within the laboratories of the Institute of Molecular and Supramolecular Chemistry and Biochemistry (ICBMS) on the Claude Bernard College of Lyon, from which two of the corporate’s three founding scientific companions, Christophe Marquette and Edwin-Joffrey Courtial, come. From 2018, they patented a know-how referred to as “by granular dynamic molding». «Normally, 3D printing is finished layer by layer. If this kind of printing works with strong supplies resembling polymers or steel, with silicone, which is a viscous liquid, it’s extra sophisticated, the stacking of layers resulting in a danger of the silicone collapsing beneath its floor. personal weight» specifies Julien Barthès, third co-founder and president of 3Deus Dynamics. A danger that requires the addition of components, “which prevents any medical use» provides the specialist within the growth of medical gadgets utilizing 3D printing.
A dynamic mould that incorporates and varieties the fabric
The innovation of 3Deus Dynamics: immerse the manufacturing head in a big tank of sand or powder functioning as a dynamic mould supporting the fabric being fashioned. Printed immediately contained in the tray, the fabric is then contained by the powder. This provides the method whole design freedom on the half to be printed.
Submit-treatment then consists of heating the powder tank to crosslink the silicone, unmoulding the half then, for medical purposes, eliminating powder residue prone to contaminate it. “Initially, we began with a sandbox and regularly we characterised an ever-increasing variety of powders, which permit us to make silicone molds with out limits in measurement and design» explains Julien Barthès.
Because the creation of its first industrial dynamic molding printer in 2022, 3DeusDynamics has already produced round 100 molds supposed for surgical preparation and utilized by totally different hospitals. “This permits the surgeon to visualise the operation and plan it, significantly when coaching new interns or surgeons. It’s a substitute for human or animal corpses.” assures the president of 3Deus Dynamics. These instruments are significantly helpful within the case of pediatric operations, typically linked to circumstances of uncommon ailments and due to this fact extra dangerous as a result of they’re much less identified.
One line for medical molds, the opposite for industrial components
The target for the corporate of 20 staff, which may have 25 by the top of the yr, is now to scale up and develop commercially to develop into a world chief within the sector. Within the new Rilleux-la-Pape manufacturing facility, two manufacturing strains might be launched, one devoted to medical molds, the opposite to industrial components, with an annual manufacturing goal of 4000 to 5000 components per yr on every ‘they.
The road devoted to medical gadgets might be put in in a clear room to fulfill the necessities of the ISO 13485 customary which governs the manufacturing of all medical gadgets, from class 1 for exterior gadgets to class 3 for implantable gadgets. “We’ve got already obtained certification for sophistication 1 medical gadgets and are actually working in the direction of acquiring certification for mushy implantable silicone gadgets (vascular prostheses, trachea implants…)” specifies Julien Barthès.
On the similar time, 3Deus Dynamics is within the means of signing contracts with aeronautics producers for the provision of seals immune to 1000°C and shielding seals towards electromagnetic interference. “Having seen that powders have a tendency to combine with silicone throughout heating, we determined to show this into a bonus for the business by creating composite supplies with useful properties (fireplace resistance, conductivity, electromagnetism)» explains the researcher. Who doesn’t intend to cease there and can be focusing on aerospace and protection.
