MANUFACTURING – 3D PRINTING (FDM) CALCULATOR
Print Time Estimate
A precise tool.
What is the Print Time Estimate & How does it work?
Fused Deposition Modeling (FDM) builds objects by extruding thermoplastic filament layer by layer. The amount of material and the speed at which the nozzle moves directly influence the total print duration.
The volume of the part, usually expressed in cubic millimeters, determines how many linear meters of filament must be deposited. Larger volumes require more passes of the print head.
Layer height controls the thickness of each deposited slice; finer layers increase resolution but also increase the number of passes. Combining volume, speed, and layer height yields a simple time estimate.
T = frac{V}{S cdot h}
V = part volume (mm³) | S = print speed (mm/s) | h = layer height (mm) | T = estimated print time (s)

Frequently Asked Questions
How does increasing the layer height affect print time?
Increasing the layer height decreases the number of layers needed to complete the print, thus reducing the overall print time.
What is the impact of nozzle speed on print duration?
A higher nozzle speed can reduce print time by depositing material faster, but it may also affect print quality if too fast.
How do I calculate the volume of my 3D model for FDM printing?
You can use 3D modeling software to measure the dimensions of your model and calculate its volume in cubic millimeters.
What is the relationship between filament diameter and print time?
A larger filament diameter means less material is needed per layer, which can reduce print time but may affect detail quality.
How does infill density influence the print duration?
Higher infill density increases the amount of material used and thus increases the print time, while lower density decreases it.
Can I estimate print time for multiple parts at once?
Yes, you can sum up the volumes of all parts and use the same parameters to estimate the total print time.
What factors should I consider when choosing a filament type for my FDM prints?
Consider the material’s strength, flexibility, heat resistance, and cost, as well as compatibility with your printer and intended application.
