摘要
以聚己内酯(PCL)为材料,采用实验方法,研究了成型温度和打印层高对PCL制品翘曲变形的影响。通过三维(3D)打印制备PCL样条,表征了3D打印PCL的力学性能,并与注射成型进行对比。结果表明,随着成型温度的升高和打印层高的增加,PCL制品的翘曲变形量呈现出先增加后减小的趋势;PCL的3D打印制品的拉伸强度、弯曲强度和断裂伸长率均高于传统注射成型工艺。
The effects of molding temperature and print height on the warpage deformation of the 3D printed part were investigated by using polycaprolactone(PCL)as a raw material.The mechanical properties of 3D printing molded parts were evaluated and compared with those of the injectionmolded part.The results indicated that the warping deformation of the 3D printed part increased at first and then decreased with the improvement of molding temperature and print height.Moreover,the 3D printing molded part achieved much higher tensile strength,flexural strength and elongation at break than the conventional injectionmolded one.
