Abstract
A process to cure and/or modify the surface of a three dimensional (3D) printed part comprising the steps of immersing a three dimensional (3D) printed part, containing reactive moieties, into a liquid bath at an elevated temperature to effect polymerization of the reactive moieties of the 3D printed part to provide a cured 3D printed part is described. The liquid bath can further contain reactive molecules that can react with the surface of the 3D printed part to provide a coating which alters the surface characteristics of the 3D printed part.
Claims28
A process to modify a three dimensional printed part comprising:
- providing a three dimensional printed part containing reactive moeities;
- providing a liquid bath, the liquid bath comprising one or more reactive molecule(s) dispersed within the liquid bath;
- immersing the three dimensional printed part containing reactive moieties into the liquid bath;
- causing the one or more reactive molecule(s) dispersed within the liquid bath to react with the reactive moeities within the three dimensional printed part, said reaction covalently bonding at least some of the one or more reactive molecule(s) to a surface of the three dimensional printed part to form a surface coating on the three dimensional printed part.
