3D  printing of high-performance polymer has been a hot topic to medical device  industry. As a peculiar resin, 3D printing of PEEK (poly-ether-ether-ketone)  filament through FDM approach remains very challenging for its high melting  temperature, high viscosity and semi-crystallinity. Over the past decade,  very few companies mastered such technology in global market. With ceaseless  efforts, YunMed has successfully completed validation and obtained excellent  mechanical properties & surface roughness for cranio-maxillo-fascial  implant samples. Such breakthrough offers surgeons personalized solution that  matches individual anatomy perfectly with affordable cost for patients.
