Object summary
Estimates assume a simple solid object. Supports, brim, and complex geometry may increase material usage by 15–30%.
What Gets Estimated
Three key outputs to help you plan any FDM print job.
Print time
Estimated hours and minutes based on volumetric flow rate (nozzle size × layer height × print speed). Includes separate infill and perimeter estimates.
Material usage
Total filament weight in grams and length in meters. Calculated from the material density and the volume of plastic actually deposited.
Cost estimate
Approximate material cost using typical filament prices per kilogram. Useful for quoting jobs and comparing materials.

Frequently Asked Questions
How accurate is the print time estimate?
The estimate is a practical approximation based on volumetric flow rate. Real slicers (Cura, PrusaSlicer, Bambu Studio) will give a more precise result because they account for acceleration, travel moves, and perimeter vs infill speeds. Treat this as a useful ballpark, not a guarantee.
What is infill density?
Infill is the internal structure of a printed part. 0% means hollow, 100% means fully solid. Most functional prints use 15–25% infill. Structural parts may need 40–60%.
What layer height should I choose?
Standard layer heights are 0.1 mm (fine detail, slow), 0.2 mm (balanced, the most common), and 0.3 mm (fast, lower quality). Layer height should be 25–75% of your nozzle diameter.
What filament diameter does this assume?
The calculator uses the industry-standard 1.75 mm filament diameter, which covers most FDM printers (Prusa, Bambu, Creality, Ender series).
Which materials are supported?
PLA (most common beginner material), ABS (high temp, warp-prone), PETG (food-safe, flexible), TPU (flexible, rubber-like), and ASA (UV-resistant, outdoor use). Densities are based on manufacturer data.
Does this account for supports or brim?
No — this calculator estimates the base object only. For complex geometry with supports, add 15–30% to the material estimate.
