Alternatively you can find suppliers for a femtosecond laser, stage, optics, software etc and put a custom system together for your needs and possibly exceed the capabilities of the nanoscribe for less cost.
Agree with Peter. Nanoscribe was our only option when purchasing one for Lancaster University, although I think the cost (for the overall package) was more than listed above.
The German company Tetra, might be another 2PP alternative to a Nanoscibe (e.g. Photonic Professional GT) printer. Not sure whether they actually sell the system or provide printing services only.
You could also use the fast LightFab 3D Printer for that (e.g. with the green high frequency laser) - but you would have to develop/investigate the photochemistry on your own: http://www.lightfab.de/index.php/id-3d_printer_standard.html
You can buy 3D printing materials here, hope you can find what you want. http://www.alfa-chemistry.com/products/3d-printing-materials-for-research-and-development-9.htm?initial=ALL
