PLAPCL夜光3D打印丝材挤出工艺与模具设计

20%,the performance of the blend material is the best.Then using 20%PLA blend,luminouspowder,silanecouplingagent,dispersant(oxidizedpolyethylenewax)andlubricant(stearicacidamide)asrawmaterials,a completely biodegradable luminous PLA/PCL blend was prepared A newtype of 3D printing wire.A small single-screw extruder and FDM3D printer were used toprepare blended wires and samples.In addition,by means of average diameter test,averagedensitytest,tensiletest,etc.,theeffectofdifferentmassratiosontheperformanceoftheblendandthemechanicalpropertiesarecharacterized.Onthisbasis,themoldstructure is drawn through the NX three-dimensionalmodeling software,the reasonable extrusion mold is designed,and the pipe extrusion moldingmold is designed.Keywords:PCL;PLA;luminous;extrusion die;design.
