PLA sheet weight calculator

Enter the dimensions of a PLA sheet and this works out its volume and weight. Solid polylactic acid. A 3D print at less than 100% infill weighs proportionally less.

Total weight
7.44kg
= Exact PLA sheet weight
Weight of one sheet
7.44
Volume of one piece
6000
Density used
1240 kg/m3
Show the working
  1. Length = 2000
  2. Width = 1000
  3. Thickness = 3
  4. Number of pieces = 1
  5. volume_mm3 = 2000 * 1000 * 3 = 6 000 000
  6. Volume of one piece = 6 000 000 / 1000 = 6000
  7. Density used = 1240 = 1240
  8. Weight of one sheet = 6 000 000 * 1240 / 1e9 = 7.44
  9. Total weight = 7.44 * 1 = 7.44

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

    The formula

    • Volume = length x width x thickness
    • Weight = volume x density, with density = 1240 kg/m3
    • One cubic millimetre of a material at 1000 kg/m3 weighs exactly one milligram, so the millimetre-to-kilogram step is a shift of the decimal point rather than a rounded factor.

    Solid polylactic acid. A 3D print at less than 100% infill weighs proportionally less.

    Dimensions are nominal. Mill tolerances on thickness, and the corner radii on formed sections, both move the real weight by a percent or two.

    Every field takes inches or feet as readily as millimetres: change the unit next to it and the conversion is done exactly before the arithmetic starts.

    Frequently asked

    What is the density of PLA?

    1240 kg/m3, which is 1.240 g/cm3. Solid polylactic acid. A 3D print at less than 100% infill weighs proportionally less.

    How do you calculate the weight of a PLA sheet?

    Volume = length x width x thickness. Multiply the volume by the density of PLA, 1240 kg/m3, taking care that both are in the same unit system.

    Can I enter dimensions in inches?

    Yes. Each dimension field has its own unit selector, and inch, foot, millimetre, centimetre and metre entries are all converted exactly before anything is multiplied.

    Where the numbers come from

    • Densities are nominal room-temperature values for the grade named, drawn from the usual mill and handbook figures.
