Research and application status of medical porous titanium alloy formed by additive manufacturing
Titanium alloy is considered as an ideal implant material for its good mechanical properties and biocompatibility.However,due to the high elastic modulus of solid titanium alloy,there is stress shielding between the implant and human bone after implantation,which can easily trigger implant loosening...

| description | Titanium alloy is considered as an ideal implant material for its good mechanical properties and biocompatibility.However,due to the high elastic modulus of solid titanium alloy,there is stress shielding between the implant and human bone after implantation,which can easily trigger implant loosening.The porous titanium alloy formed by additive manufacturing technology can solve this problem well.Starting with the design method of porous structure and the principle of additive manufacturing,the research status of mechanical properties of additive manufacturing porous titanium alloy and the research and application progress in biomedical field are reviewed,and its future development trend is prospected.Further research on porous titanium alloys for medical can be carried out in the following aspects in the future.1) Developing more advanced forming equipment to improve the forming quality and efficiency of porous titanium alloy;2) Biomimetic design is carried out on the porous structure to combine high mechanical properties with high biological properties;3) The Gibson-Ashby model was modified to obtain more accurate prediction results of mechanical properties;4) Develop new titanium alloy materials to improve the biocompatibility of porous titanium alloys. |
