Description
Part has material missing in the left to right direction. If the
part is across multiple lanes (front to back) missing material
will occur across each lane in the same relative location and
width.
Part and wall look as if something has been dragged across
the surface.
Parts have observable part material extended beyond where
the part should be in the left to right direction. Extra material
described as "flames" or "spurts" of material.
The printed part has a horizontal line through the entire part
or appears to have a missing layer of material.
The printed part has a gap in the material 1/3 and/or 2/3 of
the way across the part (front to back when standing in front
of the printer).
Parts have observable support material extended beyond
where the part should be in the left to right direction. Extra
material described as "flames" or "spurs" of material.
Material has dripped on the part or in the build chamber area.1. Perform the HMS Spout procedure.
The development of "snow" within the build chamber is
normal.
The part has a bump or a ridge of extra material 1/3 and 2/3
of the way across print platform (orientation front to back).
Clear material appears to have yellow spots.
Troubleshooting Steps
1. Perform Jet Check procedure, see Confirm Jets
1. If the jets do not clear, contact certified partner for
service.
1. Look for material buildup on the bottom of the print engine
by looking horizontally across the surface, see At a Glance
section for print engine location. If material is hanging down
use the Inspect Planarizer Blade routine to clean the
planarizer access cover. See Inspect Planarizer section for
assistance.
2. Wearing nitrile gloves, rotate the planarizer access cover
so that the planarizer blade is accessible. Clean off the edge
of the planarizer blade, See Inspect Planarizer section for
assistance. If additional dripping and/or material buildup
remains on the bottom of the print engine, contact your
certified partner for service.
1. Perform the Inspect Planarizer Blade procedure found in
this manual.
2. If problem persists, contact your certified partner for
service.
1. A pause longer than 10 minutes during a print job may
result in this defect. To eliminate, promptly remove full waste
bag and load new part and support material cartridges when
requested.
2. Email alerts can be set up to provide notification of close to
full/full waste bags as well as low/empty material cartridges.
See User Interface section for directions to set up email
alerts.
1. The printer is out of calibration, contact your certified
partner for service.
1. Perform the Inspect Planarizer Blade procedure found in
this manual.
2. If the problem persists, contact your certified partner for
service.
2. If the problem persists, contact your certified partner for
service.
1. To reduce the amount of snow within the build chamber,
increase the frequency of printer maintenance. See the
Troubleshooting and Maintenance Best Practices Section of
this manual for information.
2. If the part has been damaged from a buildup of snow,
contact your certified partner for service.
1. Contact your certified partner for service.
1. Reposition the part so that tall sections and short sections
of the print job are in different lanes (front to back when
standing in front of the machine).
2. Clear the UV lamp of excess material.
