New guy here with powdered dreams.
HP has launched some interesting inkjet printers recently with full with printerhead. They have a stationary printerhead wide enough to print the whole with of the page. They also have big ink cartridges and you probably could modify them to take continous feed/automatic topping.
Also they have set a Guiness world record in printing speed:

Think of the speed you could have (if the powder dries quick enough that is..)!
The printable area would be atleast 210x297mm (A4 paper size). For the Z you can decide what is best for your appliacation.
Do you think this could be a good contestant for a 3D powder printer solution?
The price is not so bad i think if it is usable for powder printing.
