I need some help interms of sourcing a good printer for a commissioned work. In particular I need to produce a final print of approximately 3 metres by 3 metres (~10 by 10 feet).
Do you have any recommendations. The final print needs to be delivered to australia.
It depends to some extent on what you are trying to do. There are solvent ink printers designed for billboards that are three meters wide, but they are printing in general on vinyl and at fairly low resolution because the billboards are designed to be seen from a distance.
If you want to make a fine art print on fine art paper, you'll be limited to printing in strips and piecing them together because the art papers are generally only available in widths up to around 1.5 meters. To print this size you'd be looking for someone with a "grand format" printer like a Roland, Mimaki, or Mutoh. Or, for that matter, the new Canon iPF9000. If you make three passes of 1.0 meters each, there are many large format printers to choose from.
What may clarify this a bit is thinking about how you are going to display a print this size. So called "normal" framing is out as it's nearly imposible to transport a sheet of glazing that size. The same would be true of trying to face mount to a piece of plexi that size, or dry mount to a sheet of aluminum that size. The transport will be very difficult and very expensive.
One possibility might be to print to canvas. It might be possible to seam the canvas with a heat setting adhesive (sort of like you would a rug). You could stretch the canvas over stretcher bars just like you would an oil painting. You could ship the canvas rolled in a tube with the disassembled stretcher bars and assemble and stretch on site. Just a thought.
One photographer I know who is printing this size is
Chris Jordan. His "Running the Numbers" series is printed very large, some around the size you propose. You might send him an email and ask him about his process. He'll perhaps have some interesting insights for you.
Good luck with it. Post a link and show us a picture of the installation when you get it done. I'd love to see it.
