Evonik invests in Chinese 3D-printing start-up making medical implants

German chemical firm Evonik Industries has invested in a 3D-printing start-up in China that makes implants for neuro and spine surgery. The technology enables faster recovery and fewer post-operation checks for patients and less surgical risk for doctors. Evonik says it is the lead investor in a high single-digit million-euro round of fundraising for Shanghai-based Meditool.

Meditool has developed its own hardware and software systems. The software can read and process images directly from commonly used magnetic resonance imaging (MRI) or computed tomography scan (CT) devices. A readily printable 3D model is generated by the software and sent to the printer. The implants are 3D printed with the PEEK polymer supplied by Evonik.

“Meditool’s technology pays directly into our strategy of expanding in high-tech applications for our additive manufacturing materials,” said Thomas Grosse-Puppendahl, head of the Evonik’s innovation growth field additive manufacturing.

Medical applications, he added, “are of particular interest and our high-performance polymers have already been proven as a reliable implant material in other applications such as dental.”

For patients and doctors, 3D-printed PEEK implants are revolutionary compared with metal, the current conventional solution for the orthopaedics implant market. 3D-printing allows customisation so that, for example, a plate can be made to fit precisely to the patient's skull. This reduces the likelihood that further operations will be required to adjust the size, shape or positioning of the implant. PEEK is less thermally conductive than metal, meaning that patients exposed to hot and cold temperatures won't be in danger of the implant heating up or cooling down excessively.

The material is also biocompatible and not harmful to living tissue, while allowing for CT and MRI examinations after surgery.

“Meditool is one of the pioneers in developing 3D printed PEEK medical implants,” said Ken Jin, co-founder and chief technology officer of Meditool. “Evonik has been our trusted partner in materials supply. The venture investment will be an extra boost to our endeavour to bring innovative solutions to patients and surgeons in China and the rest of the world.”

China is a key growth market for Evonik and one of the main drivers of innovation worldwide, said Claas Klasen, President Evonik Asia North region. "It not only fosters leap-frog technology, it has the population and growing middle-class to drive fast-paced demand. The Chinese market is the world's second largest for medical implants with expected annual growth rates of 10-15%," he added.

Evonik's venture capital arm has already invested in two funds in China and with Meditool, it now has its first direct investment. Co-investors in Meditool include ZN Ventures, Morningside Ventures and Puhua Capital.
