This paper describes the design and performance assessment of 3D-printed dental jaw bone implants. 3D printing has advantages in reproducing the customized shape of jaw bone implants and also allows rapid prototyping of different types of measures to enhance the jaw bone performance. 3D printing of jaw bones with biocompatible polymeric materials is promising. The curing process and trace of ejection head movement causes weak bonding planes during the 3D printing process. Consequently, the 3D-printed dental jaw bone demonstrates strong anisotropic behaviors. The experimental program that tested the strength of 3D printed jaw bone with different orientation will be discussed. It was found that the direction of printing has a major influence on the mechanical strength of printed jaw bone. Recommendations are provided for 3D-printed jaw bone to achieve the best performance.
