10.5 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 end the build at a convenient time.
10.6 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.
• Is the saturation too low?
If your parts are unusually crumbly, check to make sure your saturation levels are not set
too low for this type of part. Using a higher setting will fix this problem.
10.7 PRINTER LOOKS LIKE IT IS PRINTING, BUT IS NOT LAYING DOWN
BINDER
If you are using bleed compensation, it is not uncommon for the printer to move and lay
down little or no binder for the first few layers of a part.
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.
