SLM personalized titanium mesh covered with polytetrafluoroethylene film and preparation method of SLM personalized titanium mesh

The invention discloses an SLM personalized titanium mesh covered with a polytetrafluoroethylene film and a preparation method of the SLM personalized titanium mesh, and belongs to the technical field of guided bone regeneration barrier films. The method comprises the steps of personalized titanium mesh design, printing and annealing treatment, polishing pretreatment, ultrasonic cleaning, sand blasting surface roughening, polytetrafluoroethylene air spraying and thermocuring film forming. The defects that the SLM printing personalized titanium mesh is rough in surface, poor in biocompatibility and prone to causing foreign body reactions such as tissue fibrosis and inflammation and postoperative bone adhesion are overcome, and compared with a traditional SLM personalized titanium mesh, the SLM additive manufacturing personalized titanium mesh covered with the polytetrafluoroethylene film can effectively improve biocompatibility, reduce the cost and improve the production efficiency.
