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.

Manufacturing 3D printed objects

A method is described in which a part is placed within a chamber. Vaporized solvent is provided within the chamber such that the solvent condenses onto and treats the part. A vacuum is then applied to the chamber to extract the solvent and stop the treatment. The vacuum is controlled such that a pressure within the chamber over time has a predefined profile to prevent defects in the part from occurring due to the extraction of solvent from the part.

Treatment of parts by vaporized solvent

The present disclosure relates to a method of manufacturing a 3D printed object. The method comprises condensing solvent vapour on an outer surface of the 3D printed object. The 3D printed object comprises polymer and radiation absorber. The outer surface of the 3D printed object a) comprises pores that absorb the solvent and b) has a surface roughness, Ra, of greater than 5 μm. The method also comprises dissolving a portion of the 3D printed object to tailor the surface roughness, Ra, of the 3D printed object to a value of from 0.5 to 4 μm.
