title: [A new method of fabricating photoelastic model by rapid prototyping].
abstract: OBJECTIVE
  To explore a novel method of fabricating the photoelastic model using rapid prototyping technique.
  
  
  METHODS
  A mandible model was made by rapid prototyping with computerized three-dimensional reconstruction, then the photoelastic model with teeth was fabricated by traditional impression duplicating and mould casting.
  
  
  RESULTS
  The photoelastic model of mandible with teeth, which was fabricated indirectly by rapid prototyping, was very similar to the prototype in geometry and physical parameters. The model was of high optical sensibility and met the experimental requirements.
  
  
  CONCLUSIONS
  Photoelastic model of mandible with teeth indirectly fabricated by rapid prototyping meets the photoelastic experimental requirements well.
