Large fractures due to severe trauma, infections or tumours, as well as bone intermingling, have been a worldwide challenge in the bone field and safe and effective treatment is lacking. With advances in science and technology, the construction of artificial bone repair materials for the physiochemical properties and replicating structures through 3d printing technology is expected to provide the ideal solution to this world challenge。
After five years, xi'an particle cloud advanced materials technology co., ltd., successfully developed a 3d biological printer with autonomous intellectual property rights and pioneered the world's most advanced silkless printing method (filament free printing, ffp) to build biodegradable 3d-printed artificial bones. The artificial bone has the advantages of pore structure imitation, mechanical strength and biological compatibility, as demonstrated by a series of in vitro experiments。
The artificial bone was recently successfully completed in the osteology section of the siking hospital, affiliated with the fourth military medical university. It has been learned that the filament-free printing method, pioneered by the sian light cloud advanced materials technology ltd., can be tailored to biodegradable 3d-printed artificial bones on the basis of the size, shape and internal hole of clinical patients, as required, and can effectively improve bone conductivity, and is expected to provide evangelization in the near future for large fractured, boneless patients。
Printed biobone
The cytological inoculation in 48 hours was widespread on the surface of the artificial bone, indicating that it was conducive to cell adhesion and reproduction
