Enter your print length, filament diameter, and material density into the calculator to determine your filament usage.

Filament Usage Calculation Formula

The following formula is used to calculate the filament usage based on the input parameters.

Filament Usage = Volume * Material Density

Variables:

  • Filament Usage is the total weight of filament used (g)
  • Volume is the volume of filament extruded (cm³)
  • Material Density is the density of the filament material (g/cm³)

To calculate the filament usage, multiply the volume of the filament by the material density.

What is Filament Calculation?

Filament calculation refers to the process of determining the amount of filament required for a 3D print job. This involves understanding the print parameters, such as length, diameter, and density of the filament. Proper filament calculation ensures accurate budgeting and prevents material shortages during printing.

How to Calculate Filament Usage?

The following steps outline how to calculate the filament usage using the given formula.


  1. First, determine your print length and filament diameter.
  2. Next, determine the material density.
  3. Use the formula from above: Filament Usage = Volume * Material Density.
  4. Finally, calculate the filament usage by plugging in the values.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Print Length = 100 meters

Filament Diameter = 1.75 mm

Material Density = 1.24 g/cm³

FAQ

1. What is filament diameter?

Filament diameter refers to the thickness of the filament used in 3D printing, typically measured in millimeters.

2. How is filament usage different from filament length?

Filament usage refers to the total weight of filament used, while filament length refers to the total length of filament used.

3. How often should I use the filament calculator?

It’s helpful to use the filament calculator whenever you start a new print job, change materials, or want to estimate the cost of a print.

4. Can this calculator be used for different materials?

Yes, you can adjust the material density field to match the density of any filament material to calculate the usage accordingly.

5. Is the calculator accurate?

The calculator provides an estimate of your filament usage based on the inputs provided. For exact figures, it’s best to refer to the filament manufacturer’s specifications.
