Estimating print time
Print time is dominated by layer count × time per layer. Layer count equals model height divided by layer height. Each layer spends time on perimeters, infill, travel moves, and acceleration — slicers simulate all of that; this tool uses a simplified perimeter ÷ speed plus a small fixed overhead.
Lower layer height improves surface quality but increases time linearly. Halving layer height roughly doubles print time. Faster speeds help but may reduce quality on detailed perimeters.
Example: 100 mm tall model at 0.2 mm layers = 500 layers. At 50 mm/s and ~200 mm perimeter per layer, each layer takes ~6 seconds → about 50 minutes total before overhead.
Common questions
Why differs from my slicer estimate?
Slicers account for acceleration, retraction, infill pattern, supports, and multiple perimeters. This is a rough order-of-magnitude check only.
What print speed should I enter?
Use your outer-wall or average print speed from the slicer — typically 40–80 mm/s for PLA on consumer printers.
