Enter the average build speed, the width, height, depth, and filament size into the calculator to estimate the 3-D Print Time.

3-D Print Time Formula

The following equation is used to calculate the 3-D Print Time.

T = (W/B) * (D/S) * (H/S)

  • Where T is the total time (min)
  • W is the width of the part (mm)
  • B is the build speed (mm/min)
  • D is the depth of the build (mm)
  • S is the filament size (mm)
  • H is the height of the part (mm)

What is a 3-D Print Time?


A 3-D Print time is defined as the total time it takes for a 3-D print to complete a job, not including cooling time. The time it takes is dependent on the part size, part resolution, and build speed.

How to Calculate 3-D Print Time?

Example Problem:

The following example outlines the steps and information needed to calculate 3-D Print Time.

First, determine the build speed. In this case, the build speed is 100mm/min.

Next, determine the width of the part. This part has a width of 50mm.

Next, determine the height of the part. This part has a height of 50mm.

Next, determine the depth of the part. This part has a depth of 100mm.

Next, determine the filament size. This print is using 2mm thick filament.

Finally, calculate the build time using the formula above:

T = (W/B) * (D/S) * (H/S)

T = (50/100) * (100/2) * (50/2)

T = 625 minutes
