中文摘要：简单介绍了熔融材料堆积成形（FDM）技术的制造过程，分析FDM成形精度的影响因素，重点分析了成形工艺参数对制件精度的影响，选择关键四个工艺参数为因素，建立正交试验表L9。通过试验的数据对尺寸误差和翘曲误差进行分析，得出成形最优的工艺组合，为FDM成形提供了参考。
英文摘要：The manufacturing processes of Fused Deposition Modeling (FDM) technology is briefly introduced,the factors affecting the accuracy of FDM forming was analyzed. On the basis of analyzing the influence factors of process parameters, key four factors process parameters is selected, then，orthogonal test table L9 (34) is established, through analysis the test data of dimension error and warping errors, draw forming the optimal combination of technology, providing a reference for the FDM shape.
