Application of stereolithography prototypes for gas dynamic tests and visualization

The article presents the advantages of using a laser stereolithography apparatus (SLA) technology as compared with the traditional production technology and other rapid prototyping technologies. The authors described the seven-year experience of laboratory prototyping of experimental samples for multiple gas dynamic studies. On the basis of generalization of experience, the basic requirements for such experimental samples were formulated. During the comparison of different prototyping technologies, it was shown that the stereolithographic model meets all other requirements better.
