7.11 Part Quality Issues - Bad Surface Finish

The problems behind bad surface finish on parts will be different depending on whether the rough surface

is in the vertical plane or the horizontal plane.

7.11.1 Bad Horizontal Surface Finish

Explanation:

A bad surface finish on horizontal surfaces is usually the result of debris buildup on the Spreader Roller.

The debris sticks to the Roller and prevents it from spreading a smooth, flat layer of Core.

Solution

Clean the Spreader Roller. See Section 6.8, ’Clean The Spreader Roller’.

7.11.2 Bad Vertical Surface Finish

Explanation:

A bad surface finish on vertical surfaces is usually the result of either or both of these:

• A problem with the print heads.

• A motion problem with either the Fast Axis or the Slow Axis.
