摘要
介绍了聚合物喷射(PolyJet)彩色3D打印原理,以方环为研究对象进行彩色3D打印成型,详细分析了打印原材料使用情况及影响因素。打印所得模型包含底座、模型本身及模型四周包裹的支撑层三部分,大部分打印原材料消耗在喷孔清洁和支撑层。通过比较不同放大比例方环模型的打印结果发现,随着模型体积的增加,喷孔清洁消耗原材料的比值显著下降而模型消耗的比值则显著上升,支撑消耗的比值呈下降的趋势。喷嘴清理消耗的材料和支撑材料消耗仍然占较大的比值,超过了60%;真正用于成型模型本身的材料不到40%。减少喷孔清洁过程的材料消耗及模型表面支撑材料是PolyJet彩色3D打印推广应用急需解决的问题。
The paper first studies the PolyJet color 3D printing principle,and then takes the square ring as the research object for color 3D printing forming,and the analysis in detail was conducted on raw print material consumption. Results show that the printed model contains the base,the model itself and the support layer wrapped around the model,most of the raw print materials consumption is in spray hole cleaning and supporting layer. By comparing the printing results of square ring 3D printed in different magnification ratio,it was found that the ratio of the consumption of raw materials in spray hole cleaning decreased significantly and the ratio of raw materials in model increased significantly with the increase of model volume,and the ratio of raw materials in supporting layer decreased. The raw materials consumption in spray hole＇s cleaning and supporting layer still account for a large proportion,more than 60%,while the material used for forming the model was less than 40%. Reducing the materials consumption in sprayhole cleaning and supporting layer is the urgent problem for the generalization and application of Poly Jet color 3D printing.
