3D print shrinkage compensator
Turn a measured test print into a scale correction. Compare all three axes or use one uniform reference dimension.
Correction factors from 0.01 to 100. Recommended slicer scale from 1% to 10,000%. Proportional estimates do not repair warping, offsets or mesh geometry. Change the input or settings to update your result. Results update as you type. Up to 1,000,000 characters.

How to use 3D print shrinkage compensator
- Enter the measured inputs and select their units.
- Review the calculated dimensions, counts and rounding.
- Download the result and verify it against a sample before making the full project.
Useful next steps
Measure a reference print
Enter the CAD dimension before scaling, the resulting printed dimension and the slicer scale used for that test. Uniform mode uses one measured direction as the reference. Per axis mode calculates separate X, Y and Z corrections.
Apply one correction
A 100 mm CAD dimension printed at 100% that measures 98 mm needs a scale factor of 100/98, or about 102.0408%. Use the recommended slicer scale with the desired model size, or pre-scale the model and retain the old slicer setting. Applying both would double-correct.
