title: [RESEARCH PROGRESS OF THREE-DIMENSIONAL PRINTING POROUS SCAFFOLDS FOR BONE TISSUE ENGINEERING].
abstract: OBJECTIVE
  To summarize the research progress of several three-dimensional (3-D)-printing scaffold materials in bone tissue engineering.
  
  
  METHODS
  The recent domestic and international articles about 3-D printing scaffold materials were reviewed and summarized.
  
  
  RESULTS
  Compared with conventional manufacturing methods, 3-D printing has distinctive advantages, such as enhancing the controllability of the structure and increasing the productivity. In addition to the traditional metal and ceramic scaffolds, 3-D printing scaffolds carrying seeding cells and tissue factors as well as scaffolds filling particular drugs for special need have been paid more and more attention.
  
  
  CONCLUSIONS
  The development of 3-D printing porous scaffolds have revealed new perspectives in bone repairing. But it is still at the initial stage, more basic and clinical researches are still needed.
