Paper Abstract

The conventional industrial method for creating color transparent resin materials uses immersion of resin in heated dye diluted with water for a constant time. However, this method is not very efficient. Therefore, we developed a coloring method that uses a waveguide CO2 laser for the effective coloring of transparent resin materials. Although it is possible to color with our new method, thermal deformation in the colored parts of the material was observed. Therefore, we have examined the optimum conditions required for using laser irradiation to color resins without thermal deformation artifacts. We performed thermal analysis on the resin surface during the laser irradiation process by thermography. In this paper, we describe the construction of a coloring system that uses a waveguide CO2 laser which does not result in thermal deformation artifacts. We then employ this new system for a fundamental coloration experiment.
