Should I Use Gross Or Net Spool Weight?

Use the advertised filament weight without the empty spool, commonly 1,000 grams. The spool price should cover that same net filament amount.

Where Do Weight And Time Come From?

Use the material weight and estimated duration reported by the slicer for the actual profile, supports and infill settings.

Is Filament Length Exact?

It is a geometry estimate based on weight, diameter and density. Manufacturing tolerance, moisture and material formulation can change the real value.

Use the slicer's filament weight and print time when available. The estimate does not include labor, supports removed from the slicer total, failed-print risk beyond the waste allowance, shipping or taxes.

What Is the 3D Print Filament Cost Calculator?

The 3D Print Filament Cost Calculator combines the slicer's model weight and print time with spool price, net spool weight, material density, filament diameter, waste, printer power, electricity and machine-time allowances. It separates internal cost from an optional marked-up customer quote and estimates the filament length consumed.

How It Works

Choose a common material or enter a custom density, then enter the slicer weight and time. Add spool, electricity and machine-maintenance costs plus the waste and quote markup you use. The cost ledger updates immediately and can be copied or downloaded.

When to Use It

Use it to compare print economics, estimate stock consumption or prepare a starting quote. Add labor, design work, packaging, shipping, failed-print risk, taxes and marketplace fees separately when they apply.
