You can get your own free sample. With the sample, you could compare your print to the commercial machine.

The part we have from Stratasys is apparantly printed with 0.2mm wide extrude and 0.1mm layers. There is obvious banding under a microscope between the side-by-side extrudate leaving tiny gaps inbetween every other pass. Suggests to me a aliasing issue in the printer.
It's the version without U under lid and with the two holes. It is not watertight and you can feel air escaping when blowing into it.
Another thing I see in the microscope is a rifled appearance of the finished surface. This appears to be result from previous layer being a support-layer that has later been removed. The finish in the dimples is smooth so it has probably not been ripped apart, but dissolved. Maby they print these in bulk using both the width and heigh capability of the machine to print a big block of them, then dissolve to seperate?
It looks awsome though.
