On September 5, 2019, Evonik invested in a3D printingA start-up company that produces neurosurgery and spinal surgery implants-Headquartered in Shanghai, Mai Di Tu Medical Technology Co., Ltd. The company’s technology can speed up the recovery of patients, reduce the number of postoperative examinations, and reduce the risk of surgery. Evonik led the round of financing, which totaled several million euros.
“This is Evonik’s first direct investment in China, and it is also the first direct investment made using the second phase of Evonik’s venture capital fund launched this year,” said Bernhard Mohr, head of Evonik’s venture capital. The cooperation with Tutu is a good demonstration of how venture capital can help Evonik acquire disruptive technologies.”
Mai Ditu has developed a set of hardware and software systems that can directly read and process images from conventional magnetic resonance imaging (MRI) or computer tomography (CT) equipment. Subsequently, the system will generate an easy-to-print 3D model and send it to the printer.Finally, Evonik’s high-performance polymer polyether ether ketone (PEEK) was used as the raw material.3D printingTechnology to make implants.
For patients and doctors,3D printingCompared with the conventional metal solutions on the orthopedic implant market, the PEEK implant is undoubtedly a revolutionary product.3D printingMake customization possible.For example, by3D printingTechnology can produce a bone plate that accurately fits the patient’s skull, reducing the additional surgical risk caused by adjusting the size, shape or position of the implant. On the other hand, the thermal conductivity of PEEK is worse than that of metal. Therefore, when exposed to high temperature and low temperature environment, the risk of too high or too low temperature of the implant in the patient can be effectively reduced. In addition, PEEK material has high biocompatibility and is harmless to living tissues. After surgery, patients can be examined by CT and MRI.
“Meditu’s technology will directly help us further advance the development strategy of Evonik’s advanced raw materials in the field of additive manufacturing,” said Thomas Grosse-Puppendahl, head of Evonik’s additive manufacturing innovation growth field. “Applications in the medical field are extremely attractive. Our high-performance polymer has proven to be a reliable implant material and is suitable for other applications including dentistry.”
“China is a key growth market for Evonik and one of the main driving forces of global innovation,” said Dr. Kollsch, President of Evonik North Asia. The growing middle class is driving the rapid growth of demand. “The Chinese market is the second largest medical implant market in the world, with an estimated annual growth rate of 10-15%.
