Beschreibung
Zusammenfassung:	The present invention discloses one kind of physical and chemical method to lower the surface roughness of stereo optically cured body. The method includes the following steps: compounding resin paint through adding surfactant not more than 0.1 %, active diluent in 5-30 % and leveling agent not more than 1 % into resin and regulating the viscosity of the resin paint to 0.25-0.70 Pa.S; and coatingthe resin paint to the surface of the body to form homogeneous coating of thickness within 300 micron, so as to reduce the roughness from 6-15 micron to 3 micron. The method can eliminate the step effect of stereo optically curing, and has excellent application foreground.
