Print Time Estimator
A quick way to sanity-check a slicer's reported print time, or get a rough estimate before you slice.
What the numbers mean
The estimator computes the total length of filament path extruded by treating each layer as a series of strands with cross-section layer height × nozzle diameter. Time equals path length ÷ print speed, divided by an efficiency factor that accounts for acceleration, travels and retractions.
Choosing an efficiency factor
- 0.9–0.95: large, simple parts on a well-tuned Klipper machine
- 0.8–0.9: typical Bowden printers with default acceleration
- 0.7–0.8: small parts with many short moves
