SINTX Technologies Signs Supply Agreement with EVONIK to Manufacture Silicon Nitride–PEEK Compound for AI-Assisted, 3D-Printed Patient-Specific Implants Leave a reply Milestone enables immediate production of SiN/PEEK custom devices SALT LAKE CITY, Utah, Dec. 01, 2025 (GLOBE NEWSWIRE) — SINTX Technologies, Inc. (NASDAQ: SINT) (“SINTX” or the “Company”), an advanced ceramics and biomaterials company, today announced that it has signed a supply agreement with Evonik Corporation (“EVONIK”), a global leader in high‑performance polymers, to manufacture the Company’s proprietary silicon nitride–PEEK compound (SiN/PEEK) (U.S. Patent No. 10,806,831) engineered for AI‑assisted additive manufacturing of patient‑specific implants that will be produced using equipment already in place at SINTX’s U.S.-based production facility. Under the agreement, EVONIK will produce SiN/PEEK compound leveraging its commercial-scale capability to SINTX’s specifications, enabling the Company to immediately begin manufacturing AI‑designed, 3D‑printed, patient‑specific implants. SINTX has already received physician requests to provide humanitarian‑use vertebral body replacement (VBR) implants for orthopedic and neurosurgical oncology patients following tumor resections in the spine. In addition, the Company intends to use the SiN/PEEK compound to support regulatory clearances of patient matched and traditional subtractive manufactured implantable devices. Eric K. Olson, Chairman, President & CEO of SINTX, said, “This agreement with EVONIK is another pivotal moment for SINTX and for the field of patient‑specific implants. By combining EVONIK’s industrial‑scale PEEK polymer manufacturing expertise with SINTX’s silicon nitride biomaterial manufacturing capabilities, we can deliver next‑generation implants that address critical needs in trauma, spine, oncology, and beyond. We believe SiN/PEEK offers compelling advantages over standard PEEK, including antipathogenic surface characteristics, osteogenic potential, and improved visualization—features that matter in complex, high‑risk procedures.” Marc Knebel, head of EVONIK’s Medical Devices & Systems market segment, said, “We are excited to support SINTX in bringing a high‑performance SiN/PEEK composite filament to market for additive and subtractive manufacturing of regulated medical devices.
