You can 3D print with almost any material now.
I'm sure Staples will be using basic polymers. But, there are many other methods and materials being used now:

Sand (building molds for castings, and/or sculptures*, etc)
Metals ("selective laser sintering" as well as standard polymer deposition)
Wood fiber
Silica (glass)
And more...

If you can imagine it, it's probably being done. Some of the methods and materials just aren't exactly cheap....
