Abstract：

In order to installation and testing in the actual car, it is necessary to use lightweight materials such as engineering plastics instead of aluminum alloy to make tail lamp module based on 3D printing technology. The tail lamp module with ABS plastics and photosensitive resin materials were produced by different 3D printing motheds.Taking surface quality, appearance color and dimensional accuracy as mdicators, the control experiment was conducted. The materials and processes of tail lamp module with low surface roughness, color closed to aluminum alloy and high dimensional accuracy were determined. The results show that the gloss of photosensitive resin module printed by SLA method is higher than ABS plastic module printed by FDM mothod. The color of module made by surface painting process is closer to aluminum alloy than color mixing in raw material. And the uniform grid stiffener structure is more conducive to control the dimensional accuracy of parts than the solid filling structure.
