Zusammenfassung:	Examples of the present disclosure are directed toward methods and system for reducing surface roughness of a cured three-dimensional (3D) printed object using a localized heat source. An example method includes applying a liquid solvent to the cured 3D printed object and heating the cured 3D printed object with the liquid solvent applied thereto to a temperature below a melting point of the cured 3D printed object using a localized heat source to reduce a surface roughness of the cured 3D printed object as compared to the cured 3D printed object prior to the application of heat. Des exemples de la présente invention concernent des procédés et un système pour la réduction de la rugosité de surface d'un objet imprimé tridimensionnel (3D) durci, à l'aide d'une source de chaleur localisée. Un procédé à titre d'exemple consiste à appliquer un solvant liquide sur l'objet imprimé 3D durci et à chauffer l'objet imprimé 3D durci avec le solvant liquide appliqué sur celui-ci à une température inférieure à un point de fusion de l'objet imprimé 3D durci, à l'aide d'une source de chaleur localisée, pour réduire une rugosité de surface de l'objet imprimé 3D durci par comparaison avec l'objet imprimé 3D durci avant l'application de chaleur.
