Dynamic Nozzle Test
Perform the Dynamic Nozzle Test if you suspect that poor quality in printed
models is caused by clogged or faulty nozzles in the print heads—even if this is
not indicated by the Pattern Test.
The Dynamic Nozzle Test prints eight (8) samples on the build tray, which you
can then visually inspect. Printing the samples takes about 20 minutes.
To run the Dynamic Nozzle Test:
1. Make sure that the build tray is clear (empty).
2. From the
Options
menu, select
Dynamic Nozzle Test
, and then select the
appropriate test for the current printing mode.

3. When the samples are printed, check if they have visible gaps.

samples
❒
In the left sample shown above, there are no gaps.
❒
In the right sample shown above, there are only two gaps, which is
acceptable.
Many gaps in the sample indicates that many nozzles in the print head are not
functioning. This might indicate the need to replace the defective head. In this
case, consult with your Stratasys service provider.
Samples printed from certain Model materials in this test might not be
completely cured. Because some of the material remains in liquid (or semi-
liquid) state, you cannot check for gaps in these samples. Do not be
concerned that liquid resin remains on and around these samples.
