7.5 MY STARCH-BASED PARTS ARE UNUSUALLY “CAKEY”
• Is the saturation too high?
If your parts (especially bulky parts) are unusually difficult to depowder, too much moisture
has moved from the part into the immediately surrounding powder. The first is that you may
have the saturation levels set too high for this type of part. Using a lower maximum setting
will fix this problem.
• Was the part left in the bed too long?
If the part is delicate and requires a higher maximum setting, it will be helpful to remove the
part from the bed as soon as possible after the completion of the build. Using the delay timer
feature will allow you to cause the build to end at a convenient time.
7.6 PARTS ARE UNUSUALLY WEAK OR CRUMBLY
• Is the data file known to be without errors?
If the *.stl file is not near perfect you will have problems printing the part. Open the file in the
software and inspect it layer by layer to ensure there are no gaps and the part does not
overlap other parts.
• Is there enough binder in the feed bottles?
When you start the build, a reminder box will pop up asking you to check if there is enough
binder in the feed bottles. If you plan to start a large build make sure binder bottles are full.
7.7 PRINTER LOOKS LIKE IT IS PRINTING, BUT IS NOT LAYING DOWN
BINDER
As you begin printing, carefully watch the Z406 Printer to see if it is printing normally. It may be
that the print heads are not properly seated in the carriage. This can cause a bad connection
with the temperature sensor and the print heads will overheat. Prolonged periods of
attempting to print without binder flow will damage the print head. You will need to replace the
print heads.
