Abstract
The present invention refers to a method for polishing polyamide objects obtained by additive manufacturing or 3D printing techniques, which comprises immersion of the polyamide object in a mixture of formic acid and dichloromethane at room temperature for a period of time comprised between 5 seconds and 6 minutes. This method allows effectively elimination or reduction of the roughness of the polyamide objects obtained by additive manufacturing or 3D printing techniques, for example, obtained by techniques such as the Selective Laser Sintering (SLS) with a simple procedure which does not require neither high temperatures nor extended treatment times. The present invention also refers to the object obtainable according to such method.
