3D Print Shrinkage & Scale Compensation Calculator
Calculate the exact scale percentage to apply in your slicer or CAD software to hit your target dimensions after material shrinkage.
Scale by material shrinkage rate
ℹ️ ABS shrinks significantly - 0.6-1.0% depending on part size. Larger parts need more compensation.
