1. A system for providing a liquefier nozzle flexure to at least enable ironing of a 3D print, comprising:
a controllable print head for providing the 3D print;
a liquefier capable of liquefying deposit material for providing the 3D print;
the liquefier nozzle flexure having a first side proximal to the liquefier, a second side distal to the liquefier, and a top side mounted to the controllable print head only proximate to the second side of the liquefier nozzle flexure; and
a liquefier mount connection that operatively connects the liquefier nozzle flexure to the liquefier, the liquefier nozzle flexure extending solely from the first side of the liquefier nozzle flexure to a far side of the liquefier such that a distance between the controllable print head and the liquefier is allowed by the liquefier nozzle flexure to vary when a resistance is encountered at a print nozzle tip.
