Tackiness

Tackiness

Sometimes, after printing, the surfaces of the model are tacky or sticky.

Possible Causes and Solutions

Low UV Intensity

The UV lamp might flicker, or its intensity might be too low. In this case, it does not cure the material properly, resulting in surface stickiness.

Solution: Run the UV Lamp Calibration wizard to adjust the UV intensity level. If the UV lamp cannot be calibrated, you might need to replace the UV lamp.  See the user guide for guidelines.

Preventive measures: In the printer application, a pop-up message reminds you to test the lamps and calibrate the level of UV intensity after every 300 hours of printing. See the user guide for details.
