Hydrographic Printing is transferring colored inks on a film to the surface of an object. The film is placed on water and activated with a chemical that allows it to Stick to an object being physically pushed onto it.
Pysical transfering of inkjet printed pictures onto a object. Amazing results and much stronger then the usual powder created 3D printed objects.
An amazing advancment, 3D printing that changes it's shape when submersed in water. The process uses cellulose fibers which, when aligned in a particular way and exposed to water, swell in order to change shape.

This is a amazing piece of work made by Joe Grundfast in Zbrush. The Picture link will bring you to a 3D printed version of his war machine and the other is a link to his webpage outlining his process of making the figure.
A fellow by the name of Hobbyman on Instructables has come up with a rather unique way of making much stronger parts using 3D printed parts as a base. I have used the method myself on my Mega Prusa I3 design and the part has never broken. Follow the link to his instructables page for more info.
