How to Calculate 3D Print Time Estimator

What is 3D Print Time Estimator?

The 3D Print Time Estimator predicts FDM print duration from model volume, layer height, infill percentage, and print speed. Real-world print time depends on extrusion volumetric rate (mm³/s) and slicer settings; this calculator gives a baseline ±20% estimate before slicing.

Formula

Time (min) = Volume × (0.3 + 0.7 × Infill) / (Speed × Layer × 0.4 × 60) × 60
