Maintenance & Troubleshooting Manual
Problem/Symptom:
Part Won’t Stick to the Plate
Potential Cause
Diagnostic/Remedy Actions
Plate is dirty
Clean the plate using Acetone (when printing ABS) or
alcohol-based cleaners (PLA) or just with warm water and
soap (PA) to remove fingerprints, glue leftovers and other
adhesion improvement substances
Z offset is too big.
Decrease Z offset setting in your slicer
First layer speed is too high.
Decrease first layer speed in your slicer settings
Polymer in use is not compatible
with printing bed surface.
Change surface or use an adhesion improvement product
(hairspray or any other product)
Printing plate is too cold.
Increase thermal settings (plate and heated chamber)
Part has very small “foot area”
compared to height.
Decrease printing speed Increase layer thickness Enlarge
support / use brim
Check alternative part orientation
Be sure that door is closed
Close Door - if not, part may detach from plate and/or
delaminate"
Problem/Symptom: Part Contamination
–
Lacks Color Separation
Potential Cause
Diagnostic/Remedy Actions
Plate is dirty
Clean the plate using Acetone (when printing ABS) or
alcohol-based cleaners (PLA) or just with warm water and
soap (PA) to remove fingerprints, glue leftovers and other
adhesion improvement substances
Extrusion temp is too high
When an extruder is deselected, if temperature is too high
makes for longer liquid polymer state (aka: oozing) than
flows out of nozzle due to gravity. Decrease printing and/or
preheating temperature.
Print speed is too high
Residual nozzle pressure isn't neutralized with retraction.
Slow down printing speed
No nozzle priming strategy enabled
Use one of the possible slicing solutions (prime pillar, wall,
…) that let you keep a cleaner part
Bad Z nozzle leveling
Be sure to correctly perform the calibration of
Z nozzle alignment
Bad XY nozzle alignment
Be sure to correctly perform the XY nozzle alignment
Problem/Symptom: Part Dimensional Issues
–
Big or Small
Potential Cause
Diagnostic/Remedy Actions
Polymer has higher than expected
shrinkage ratio
Increase your part size in slicing software
Change polymer
Lower printing temperature (if possible)
Use part ventilation
Use heated chamber
