Abstract: Apparatus is described comprising a treatment chamber, a pump, a condenser and a secondary chamber. The treatment chamber comprises an interior into which an article to be treated can be disposed. The condenser, the pump and the secondary chamber are is in fluid communication with the treatment chamber in a closed loop to form a vapor extraction part of the apparatus. The apparatus may comprise a controller to control the operation of the apparatus automatically.

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.

Abstract: According to an example, a recoater for a three-dimensional (3D) printer may include a cylindrical element having a surface to spread build material particles. The build material particles may have a specified average dimension and the surface may include a plurality of depressions that have dimensions that are smaller than the specified average dimension of the build material particles.

Abstract: 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.

Abstract: 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.
