基于Moldflow和UDE的打印机上盖翘曲变形工艺参数优化 Abstract Inthispaper,weaimedtooptimizetheprocessparametersforthe3DprintercoverwarpagedeformationusingMoldflowandUDE.The3DprintingprocesswassimulatedandanalyzedusingMoldflow,andthewarpagedeformationofthecoverwasanalyzedusingUDE.Wethenusedtheresultsofthesimulationtooptimizetheprocessparameters.Theresultsshowedthatoptimizingtheprocessparameterscansignificantlyreducethewarpagedeformationofthe3Dprintercover,therebyimprovingthequalityofthe3Dprintedparts. Introduction Withthegrowingpopularityof3Dprinting,thequalityof3Dprintedpartshasbecomemoreimportantthanever.Oneofthemostcommonqualityissueswith3Dprintedpartsiswarpagedeformation.Thewarpagedeformationofa3Dprintedpartoccurswhenthepartcoolsandsolidifiesunevenly,causingittobend,twist,orwarp.Thisdeformationcancauseaparttobeunusableandcannegativelyimpacttheoverallqualityofthefinalproduct.
