7.8 Part Quality Issues Streaky/Striped Parts, Delamination, Weak
Parts
Explanation:
In a
color
print job, streaky or striped parts are easy to identify (see photo below). The
streaks or stripes are caused either by powder buildup on the print head, a failed print head, or an electri-
cal issue within the printer. With a
monochrome
printer, this is harder to see, and in fact often shows up as
weak parts, or parts that delaminate.
Delamination (layers splitting apart) may be due to a print head that is caked with powder, or a pause in
network communications.
Solution - Both:
•
Clean the service station. See
Section 3.4, ’Clean The Service Station’
.
•
Ensure the printer has cleaning solution.
•
Clean the Fast Axis Rails of any debris and reboot the printer. See
Section 3.3, ’Clean The Fast
Axis Rails and Carriage’
.
If the problem persists,
•
Clean the pogo pins and the print head contacts.
Additional Solution - Delamination
Check your PC settings. The printer may be pausing as it waits for additional data from the PC. While
pausing, the printed part begins to dry and as a result the next layer does not stick to the last layer printed.
Your PC should be dedicated to ZPrint. Your PC Power Management software should be completely shut
off.
