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: A method of applying a cap to a printhead may comprise selectively applying an immiscible fluid to a surface of a printhead in which the immiscible fluid caps a number of nozzles on a number of nozzles defined within the printhead. A printhead may comprise a layer of immiscible fluid in which the immiscible fluid is selectively applied to the surface of the printhead and in which the immiscible fluid caps a number of nozzles defined within the printhead. A printer may comprise a printhead comprising a number of nozzles, an immiscible fluid applicator, and a processor to instruction the immiscible fluid applicator to apply a layer of immiscible fluid to the surface of the printhead.

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.

Abstract: The present disclosure relates a method of chemical polishing a 3D printed object. The method comprises treating a 3D printed object with solvent to reduce the surface roughness of the 3D printed object, and controlling the Youngs modulus of the 3D printed object within a target value by selectively removing at least part of the solvent from the 3D printed object.
