摘要
为探索熔融沉积快速成型技术(FDM)的工艺参数对聚乳酸(PLA)制件成型尺寸误差的影响规律,通过逆向数据采集方法对制件的长度误差、宽度误差、厚度误差进行测量对比,在4 个单一工艺参数(外墙打印速度、外墙线宽、打印温度、打印层高)变化对尺寸误差影响分析的基础上,采用响应面法对筛选出的3 个主要因素进行交互实验与分析.结果表明,长度误差受工艺参数的影响最大,其次是厚度误差,工艺参数对长度误差、宽度误差以及厚度误差的影响程度的排序均为:打印层高>打印温度>外墙线宽.
Abstract
To explore the influences of process parameters of the fused deposition modeling(FDM)on the dimensional errors in the molding of polylactic acid(PLA)parts,the length errors,width errors and thickness errors of the parts were measured and compared by the reverse data acquisition method.The influences of four kinds of single process parameters(outer wall print speed,outer wall line width,printing temperature and printing layer height)on the dimensional errors were analyzed.Then,the response surface method was used to conduct interaction experiments and analyses on the main three factors screened out.The results show that the length errors are most affected by the process parameters,followed by the thickness errors.The orders of the influence degrees of process parameters on the length errors,width errors and thickness errors are the same,which is as following:printing layer height>printing temperature>outer wall line width.
