Filament Shrinkage Percentage: PLA, PETG, ABS, ASA, TPU
Quick answer
How much does filament shrink? Typical 3D printing shrinkage percentage is PLA 0.3%, PETG 0.4%, TPU 0.6%, ASA 0.7%, Polycarbonate 0.7%, ABS 0.8%, Nylon (PA) 1.5%. To hit a target size, scale the model by 100 / (100 - shrinkage %): a 100 mm ABS part is modelled at 100.81 mm. These are typical values; a measured test part from your own machine beats any table.
| Material | Typical shrinkage | Normal range | Scale factor | Model size for 100 mm |
|---|---|---|---|---|
| PLA | 0.3% | 0.2 to 0.4% | 100.3% | 100.3 mm |
| PETG | 0.4% | 0.2 to 0.6% | 100.4% | 100.4 mm |
| Standard resin | 0.4% | 0.2 to 0.8% | 100.4% | 100.4 mm |
| TPU | 0.6% | 0.3 to 1% | 100.6% | 100.6 mm |
| ASA | 0.7% | 0.5 to 0.9% | 100.7% | 100.7 mm |
| Polycarbonate | 0.7% | 0.5 to 0.9% | 100.7% | 100.7 mm |
| ABS | 0.8% | 0.6 to 1% | 100.81% | 100.81 mm |
| Nylon (PA) | 1.5% | 1 to 2% | 101.52% | 101.52 mm |

Common questions
How much does TPU shrink?
TPU typically shrinks about 0.6% (normal range 0.3 to 1%). To compensate, scale the model to 100.6% of the target size, so a 100 mm TPU part is modelled at 100.6 mm. Flexible filament varies more between brands than rigid filament, so print a test piece first.
What is the PETG shrinkage percentage?
PETG typically shrinks about 0.4% (normal range 0.2 to 0.6%). PETG shrinkage compensation is a scale factor of 100.4%, or 100.4 mm for a 100 mm dimension.
What are ASA and ABS shrinkage percentages, and how do I compensate?
ASA typically shrinks about 0.7% (normal range 0.5 to 0.9%) and ABS about 0.8% (normal range 0.6 to 1%). ASA shrinkage compensation is 100.7% and ABS is 100.81%, applied as an overall scale factor in the slicer. A heated, enclosed chamber reduces warping and makes the result more repeatable.
Does shrinkage change with part size?
Shrinkage is a percentage, so a larger part shrinks by a larger absolute amount: 0.8% of 200 mm is 1.6 mm, while 0.8% of 20 mm is 0.16 mm. Use the shrinkage compensation calculator for your exact dimension.
