Researchers from the University of Calgary have developed a “liquid in liquid” 3D printing material.

This may be one of the most unusual approaches to 3D printing I’ve yet seen: printing liquids inside of a liquid medium. You may initially think this is impossible, as the liquids would mix and disperse immediately, and that would be the normal case.
There have been methods developed previously to “print” drops. Imagine a syringe moving to a position inside a liquid chamber, and issuing a single drop. That works, but you cannot print continuously.
However, here we have a new material that can maintain its structure and can thus be positioned in 3D space within a liquid and apparently printed continuously.
