A METHOD FOR IMPROVING THE INNER SURFACE QUALITY OF A 3D PRINTOUT

摘要

The present invention provides a method for improving the inner surface quality of a 3D printout, comprising steps of: chemically plating the printout by using a first material to deposit a first material layer on the surface of the printout, and putting the printout into a vacuum furnace for thermal treatment. The present invention can implement filling of surface holes and tiny recesses on the surface of a printout with an internal trench structure, reduce the roughness of inner and outer surfaces of the printout and improve the surface quality of the inner and outer surfaces of the printout. In addition, since the thickness of the first material layer coated on the substrate of the printout is smaller than 5 micrometers, the internal structure, appearance, and dimensional accuracy of the printout remain unaffected.
