Horizontal Hot air curtain for layer curing on up-down movable platform builds

Has anyone built such a system on a movable up-down print bed build such as a gantry style H-bot or coreXY to cure a deposited layer of epoxy or other thermally curable materials such as silicone?

The horizontal hot air knife /hot air curtain is placed concentric to the build platform at the dispense/extrusion height. This cures the layer well enough so that is is sufficiently cured to accept the next layer on top of it.

This is especially useful while 3D printing with liquids or elastomers such as epoxy or silicone, so that the layer underneath is sufficiently cured and solidified to receive and support the next layer on top of it.
