Filament Density Calculator
Determine the density of an unknown filament by measuring a known length and weight.
How It Works
Cut a known length of filament, weigh it precisely, and enter the diameter. The calculator divides weight by volume to find density, helping identify unknown materials.
Formula
Density (g/cm3) = Weight (g) / (PI x (diameter/2)^2 x length (cm))
Frequently Asked Questions
Why does density matter?
Density determines how much a given length of filament weighs. Accurate density is needed to convert between grams and meters for cost and usage calculations.
How accurate is this method?
With a digital scale accurate to 0.01g and a 50cm sample, you can determine density to within 2-3%, sufficient for most calculations.
