Research On Key Techniques Of Color Stereo Lithography

Color Rapid Prototyping is based on Rapid Prototyping. And it is an advanced manufacturing technology. The appearance of colored prototype makes communication more convenient and efficient. Therefore color rapid prototyping attracts more and more attention. Besides the technologies of laser, NC, CAD/CAM and new material, the interaction of different materials should be considered in Color Rapid Prototyping. Based on SL technique, some research is performed on the machining influence when different material is put into the host material.The model made by SL is translucent. The research described in this dissertation is about the change of single layer depth and mechanical property when the coloring agent is interfused into the photo-resin.This dissertation introduces the current development of color rapid prototyping and some negative factors firstly. And then Color SL is introduced in detail. Afterwards the author presents the character of resin and chooses some kinds of coloring agents. The experiments are carried out to compare the change of single layer depth of cured resin when the coloring agent is interfused into photo-resin. Furthermore several coloring agents are modified to face the interfusion problem. Expected slice height is confirmed. Finally, simple set up is designed to produce the color prototypes for the mechanical property testing.This dissertation performs some basic work on material of Color SL, and shows the influence of coloring agents on the photo-resin. It will greatly promote the development of Color SL technology.
