Why can't we have FDM printers print in Metal Filament?

[ImaginationProgress]

The first uses a two stage process. First stage is to print a clay made up almost but not entirely of metal particles. You use a paste extruder, such as this one from thingiverse, loaded with a metallic clay such as this (which evidently sees a lot of use by jewelry makers). Second stage is to fire the piece in a kiln. You end up with a metal piece.

What other materials besides metal would this clay be made up of? What happens to the clay once the piece is fired in a kiln? Would the object change shape/shrink when heated?

I'm about as familiar with the material as you are, but from the ebay listing: "Shrinkage during firing is about 10% to 18%, and the purity of the fired clay is 99.9% which can be laser hallmarked if required by most UK assay offices." Evidently the clay is made up of a binder, water and fine particles of metal.

We have been able to do some research work on this topic and tried to find out the solutions to overcome the problems associated with the 3D Metal Printing. The complete details have been mentioned in the link given below.
