Abstract
The present disclosure relates to a method of manufacturing a 3D printed object. The method comprises treating an outer surface of a 3D printed object with a dye condensing solvent vapour on the treated outer surface; and dissolving a portion of the treated outer surface in the condensed solvent to reduce the surface roughness of the 3D printed object.
Claims11
A method of manufacturing a 3D printed object, comprising:
- treating an outer surface of a 3D printed object with a dye that penetrates the outer surface to provide a barrier to a subsequently applied condensed solvent;
- condensing solvent vapour on the treated outer surface, thereby forming the condensed solvent;
- dissolving a portion of the treated outer surface in the condensed solvent to reduce a surface roughness of the 3D printed object, whereby the barrier reduces penetration of the condensed solvent into a core of the 3D printed object;
- and
- removing at least a portion of the condensed solvent from the 3D printed object to provide the 3D printed object with a residual solvent concentration of less than about 0.7 mg/cm2.
