Study on the Solidified Depth Parameters Capable of Quantitative Comparison of Photopolymers for Three Dimensional Photofabrication

Abstract

Accuracy improvement of the models created by three dimensional photofabrication depends on the conditions whether or not a machine uses the proper photopolymer and selects laser power and scanning speed to minimize the depth variation which is caused by the laser power's and the scanning speed's stabilities. The experimental equation between exposure condition and solidified shape enables the quantitative comparison of photopolymers. Several experiments show that the solidified depth is expressed by four parameter coefficients, laser power and scanning speed. This paper discusses the comparison method of solidified depth stability using this relation.
