Re: Info Inquiry on the ZCORP z402 3D Printer

1.) We have had our machine since July 1997 it has been very dependable for us. No
significant down time due to problems with the machine. Less than a week total over
two years.

2.) The machine runs like a charm even after extended use.

3.) Print head life is related to the density of the parts being built and how busy
the machine is. We have found that we replace a head about once a month on average. We
use the machine a lot so your situation may be different.

4.)We only have the Z402 as far as 3D Printers go, but we have clients that use the
wax based machines and they seem to always be broken.

5.) With the new materials they are working on, we are seeing some very exciting ways
to use green parts for castings. In some cases, secondary steps can be eliminated
completely. Durability, fine detail and accuracy are significantly better than with
the older materials.

Hope this helps!
