3D Print Time Estimator
Compare 3D print settings before you slice.
A QUICK WALKTHROUGH
How to use this tool
- Enter model height, footprint area, layer height, infill, and print speed.
- Estimate the duration and layer count.
- Compare settings before confirming them in your slicer.
How it works
Assumes a constant square cross-section, 0.4 mm line width, two walls, and four solid layers at each end, capped at the total layers. Layers = ceil(height / layer height). Convert cm² to mm² by multiplying by 100; inner area = max(0, sqrt(area) − 1.6 mm)². Solid layers use the full area; others use wall area plus infill × inner area. Divide their summed areas by line width and speed for extrusion seconds.
Scope
It excludes travel, supports, retractions, warm-up, cooling, acceleration, and printer-specific behavior. Use a slicer for a production estimate.
GOOD TO KNOW
Common questions
Is this the final print time?
No. It is a browser-local comparison estimate. A slicer has the detailed toolpath needed for a final estimate.
