Could be just below freezing, lay down water chilled to just above freezing and hit it with liquid N2 at the layering point (like a nozzle cooling fan).That would be an interesting challenge- build a 3-D printer for ice
Difficult to design a mechanism that would work at freezing temps- couldn't use rubber belts they'd be hard as a rock
