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.

A method of chemical polishing a 3D printed object, said method comprising:
- treating a 3D printed object with solvent to reduce the surface roughness of the 3D printed object by contacting the 3D printed object with solvent vapor and condensing the vapor on the 3D printed object;
- and
- controlling the Young's modulus of the 3D printed object within a target value by selectively removing at least part of the solvent from the 3D printed object by heating the 3D printed object at 120° C. for a period of time ranging from 1 hour to 3 hours, such that the 3D printed object contains 0.5 mg/cm2 to 3 mg/cm2 of residual solvent.
