Enter the weight of the printed object (grams) and the volume of filament used (mm^3) into the Filament Density Calculator. The calculator will evaluate and display the Filament Density. 

Filament Density Formula

The following formula is used to calculate the Filament Density. 

FD = W / VF

  • Where FD is the Filament Density (g/mm^3)
  • W is the weight of the printed object (grams) 
  • VF is the volume of filament used (mm^3) 

How to Calculate Filament Density?

The following example problems outline how to calculate Filament Density.

Example Problem #1:

  1. First, determine the weight of the printed object (grams). 
    1. The weight of the printed object (grams) is given as: 20.
  2. Next, determine the volume of filament used (mm^3). 
    1. The volume of filament used (mm^3) is provided as: 10.
  3. Finally, calculate the Filament Density using the equation above: 

FD = W / VF

The values given above are inserted into the equation below:

FD = 20 / 10 = 2 (g/mm^3)


Example Problem #2: 

For this problem, the variables needed are provided below:

weight of printed object (grams) = 19

volume of filament used (mm^3) = 431

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

FD = W / VF = ?
