ABS typically shrinks 0.5-1.0% (average 0.8%). A 100mm part may come out 99.2mm. Scale up by 100.8% in your slicer to compensate. Enclosed printers reduce shrinkage.
| Material | Shrinkage % | Scale Factor | 100mm Becomes |
|---|---|---|---|
| PLA | 0.3% | 100.3% | 99.7mm |
| ABS | 0.8% | 100.803% | 99.2mm |
| Nylon | 1.5% | 101.523% | 98.5mm |
| PP | 2.0% | 102.041% | 98.0mm |
Scale your model by 100/(100-shrinkage%). For 0.8% shrinkage: scale = 100/99.2 = 100.806%. Apply uniform XYZ scaling in your slicer.
Yes. Higher print temperatures, faster cooling, and thicker layers increase shrinkage. Enclosed printers with heated chambers reduce ABS/nylon shrinkage significantly.
PLA has the least shrinkage at 0.2-0.5%, making it the most dimensionally accurate FDM material. PETG is also low at 0.2-0.6%. Nylon and PP shrink the most.
