How to Use This Calculator
- Start by filling in the input fields below. Results update instantly as you type, so you can experiment with different values to see how they affect the outcome.
- Printer Type — Type of 3D printer being used. SLA is most precise, FDM is least precise. Choose from: FDM (Fused Deposition), SLA / MSLA (Resin), SLS (Selective Laser Sintering). default: 1.
- Material — Print material. Different materials have different shrinkage rates as they cool or cure. Choose from: PLA, ABS, PETG, Nylon, Standard Resin, Tough Resin. default: 1.
- Nominal Dimension — The target dimension of the feature you are designing (e.g., hole diameter, peg width). Accepts values from 1 mm to 500 mm (default: 20 mm).
- Once all inputs are set, review your results in the Results panel. Here's what each output means:
- Expected Tolerance (±) — shown as a numeric value. This is the primary result of this calculator.
- Shrinkage Amount — shown as a numeric value. This is the primary result of this calculator.
- Minimum Dimension — shown as a numeric value.
