Abstract
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.
Claims15
A method comprising:
- applying a liquid solvent to a cured three-dimensional (3D) printed object, the liquid solvent including an alcohol;
- 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 applying localized vectors of heat 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.
A method comprising:
- forming a cured three-dimensional (3D) printed object;
- applying a liquid solvent to the cured 3D printed object, the solvent including an alcohol;
- 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 applying localized vectors of heat;
- and
- after between about one second to about five minutes, removing the heat from the cured 3D printed object 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.
A system comprising:
- a cured three-dimensional (3D) printed object formed by an additive printing process;
- a solvent source to apply a solvent in a liquid form to the cured 3D printed object, the solvent including an alcohol;
- a localized heat source to apply localized vectors of heat to the cured 3D printed object;
- and
- processor circuitry configured to cause the localized heat source to heat the cured 3D printed object with the solvent applied thereto to a temperature below a melting point of a build material forming the cured 3D printed object for between about one second to about five minutes 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.
