With today's technology, we have the ability to 3D print in plastics, metals, ceramics, and even Nutella. Each and every day it seems as though we are introduced to a new type of material that is able to either be extruded from a 3D printer or printed via another type of laser or light processing technology. It was only a matter of time before someone would come up with the clever idea of trying to 3D print objects out of ice cream.
Three students at MIT (Kyle Hounsell, Kristine Bunker, and David Donghyun Kim), as part of a project for Professor John Hart's graduate class on additive manufacturing, in fact did come up with this tasty idea. Hart's class focuses on the fundamentals of additive processing of polymers, metals, and ceramics, as well as machine designs and control strategies, 3D geometry representations and metrology, material properties and digital assembly. Students broke off into groups to create new 3D printing technologies. Kyle, Kristine, and David decided to try and create a machine that could 3D print soft serve ice cream.
Hey, look. A page that has 8 images that are actually useful. Okay, now I'm going to grab something sweet.

Upon reading your question, my first thought was *flux* for soldering surface-mount electronics.
(It doesn't need to be anywhere near this cold, though it does have a longer shelf life if you keep it cool.)
Flux is also typically applied with a stencil, so I don't know that you'd gain much with a printer that deposits it.
So: Some kind of liquidy/pasty stuff that you want to stay in place until the non-cold part of that process is begun.
