StereoLithography로 3차원 형상가공을 위한 레이저 조사경로 생성에 관한 연구

A study on laser scan path generation for manufacturing 3-dimensional body using StereoLithography

This paper deals with the generation of laser scan path for manufacturing 3-dimensional body using StereoLithography. The purpose of this study is to develop one module of the StersoLithography system(SLA) for Rapid Protyping and Manufacturing. AutoCAD system is used to supply CAD information from model. The X-Y controller which was made for a special purpose is used to test this system. The system software developed is composed of 3 main modules, the first module is calculating the boundary point os laser scan path. The scound module is generating final output file which is used to down load on the controller. The result of this study shows a good algorithm to generate laser scan path on the basis of simple mathematical background.
