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.
Claims24
A process to cure and/or modify a three dimensional (3D) printed part comprising the steps:
- providing a three dimensional printed part containing reactive moieties, and comprising a thermal initiator disposed within the three dimensional printed part, and
- immersing the three dimensional (3D) printed part containing reactive moieties into a liquid bath to effect polymerization of the reactive moieties and change the degree of polymerization of the 3D printed part.
