An important but often overlocked step when tuning a filament profile is shrinkage compensation for dimensional accuracy

The last step I do when setting up a filament profile is calculating the material shrinkage. After all other filament setting are dialed in I always print this model to help ensure the dimensional accuracy.

Slicer settings

Select the wall thickness, top/bottom shell thickness and infill percentage you intend to use for your project. In the material setting make sure the Shrinkage (XY) and Shrinkage (Z) are set to 100%

 

After printing wait until the test print has cooled completely before measuring, this is very important when calibrating materials like ABS or ASA.

 

This is the formula I found to calculate shrinkage. 

Shrinkage % = 100 - (Measured length / Target length x 100)

 

Set the new value.

 

Re-print the test bar with the new settings.
