摘　　要：从三维(3D)打印技术中熔融沉积快速成型(FDM)的成型原理出发,先分析薄板塑件在成型过程中形成表面质量误差的主要因素,并设计相关实验,主要研究了分层厚度与挤出速度对薄板成型表面精度的影响,以及打印速度对表面粗糙度的影响.并分析得到了零件精度误差最小的参数组合为:分层厚度为0.2 mm、挤出速度为30 mm/s、打印速度为40 mm/s,从而进一步得到了优化制件加工参数的一般原则。This article analyzed the main factors which influenced the surface error of thin parts molded by 3D printing on the basis of the fused deposition modeling （FDM） method, and then the relevant experiments were designed. The effects of layer thickness and extrusion speed on the surface precision of the thin part were investigated, and the influence of printing speed on the surface roughness was evaluated. The results indicated that the parameters for the minimum errors in precision of parts could be determined as a layer thickness of 0. 2 mm, an extrusion speed of 30 mm/s and a printing speed of 40 mm/s. As a result, the general principles were achieved for the optimization of processing parameters.
