Abstract
A printing system includes a liquid ejector configured to deposit a curable layer on a surface of a substrate, the layer having a free surface and an interface between the layer and the substrate. A pre-curing device pre-cures the layer such that a first region closer to the free surface is less cured than a second region closer to the interface. The curing device includes a pre-curing initiator source configured to provide a pre-curing initiator that polymerizes the layer. The curing device also includes a pre-curing inhibitor source configured to deliver an inhibitor that inhibits polymerization of the layer. A particle delivery device delivers particles to the layer after the layer is pre-cured.
