摘　　要：根据三嵌段聚合物聚氧乙烯-聚氧丙烯-聚氧乙烯(F127)与紫外光固化单体聚乙二醇(400)二丙烯酸酯(SR344)间的协同效应,制备了一种用于紫外光固化三维打印(3DP)的支撑材料,研究了喷射稳定性对支撑材料喷射面表面形貌的影响,支撑材料的力学性能以及固化收缩率等因素对成形精度的影响;并用扫描电镜(SEM)观察了支撑材料与实体材料接触面分离情况。结果表明,支撑材料固化后具有一定的力学性能,成形尺寸稳定,与实体材料容易分离且不影响模型的表面精度。In this paper,an ultraviolet（UV） curable support material pre-polymer for three dimensional printing（3DP） was prepared based on the synergistic effect between PEO-PPO-PEO tri-block copolymer（F127） and polyethylene glycol 400 di-acrylate（SR344）.The effect of stabilizer on surface morphology of support material and the effect of F127 on Shrinkage were studied.Then the contact surface profile of support material to building material was investigatied by scanning electron microscope（SEM）.The result shows that the forming precision of building model is improved;furthermore,the support material can be removed easily from building model without spoiling the model.
