Complex Geometry in additive manufacturing design
The bone repairing is very important. Due to the age and other factors, bones suffer from bone defects and disorders.
According to the Journal of Materials Chemistry,”The aim of this study is to set out to solve these problems by applying a modified 3D-printing method to prepare highly uniform CS scaffolds with controllable pore structure and improved mechanical strength. The in vivo osteogenesis of the prepared 3D-printed CS scaffolds was further investigated by implanting them in the femur defects of rats. The results show that the CS scaffolds prepared by the modified 3D-printing method have uniform scaffold morphology. The pore size and pore structure of CS scaffolds can be efficiently adjusted. The comprehensive strength of 3D-printed CS scaffolds is around 120 times that of conventional”.
According to the 3D Printing Professor,”the Quetzalcoatlus model of 3D printed Dinosaur”.
According to Rahul Panat, Associate Professor, Mechanical Engineering, Carnegie Mellon University,”I don’t believe anybody until now has used 3D printing to create these kinds of complex structures”.
