Extrusion Multiplier Calculator

Formula

To calculate the new Extrusion Multiplier (\(EM_{\text{new}}\)):

\[ EM_{\text{new}} = \left(\frac{EW_{\text{expected}}}{EW_{\text{measured}}}\right) \times EM_{\text{current}} \]

Where:

\(EM_{\text{new}}\) is the new extrusion multiplier
\(EW_{\text{expected}}\) is the expected width of the filament extrusion (mm)
\(EW_{\text{measured}}\) is the measured width of the filament extrusion (mm)
\(EM_{\text{current}}\) is the current extrusion multiplier set in the 3D printer

What is an Extrusion Multiplier?

The extrusion multiplier is a setting in 3D printing that adjusts the amount of filament that is extruded during a print. It is used to calibrate the printer to ensure that the actual amount of plastic being laid down matches the expected amount. This is important for the accuracy and quality of the print. A well-calibrated extrusion multiplier helps in achieving the right dimensions and surface finish of the printed object.

Example Calculation 1

Let's assume the following values:

Expected Width of Filament Extrusion (\(EW_{\text{expected}}\)) = 0.45 mm
Measured Width of Filament Extrusion (\(EW_{\text{measured}}\)) = 0.50 mm
Current Extrusion Multiplier (\(EM_{\text{current}}\)) = 1.00

Using the formula:

\[ EM_{\text{new}} = \left(\frac{0.45}{0.50}\right) \times 1.00 = 0.90 \]

The new extrusion multiplier is 0.90.

Example Calculation 2

Let's assume the following values:

Expected Width of Filament Extrusion (\(EW_{\text{expected}}\)) = 0.40 mm
Measured Width of Filament Extrusion (\(EW_{\text{measured}}\)) = 0.35 mm
Current Extrusion Multiplier (\(EM_{\text{current}}\)) = 1.05

Using the formula:

\[ EM_{\text{new}} = \left(\frac{0.40}{0.35}\right) \times 1.05 = 1.20 \]

The new extrusion multiplier is 1.20.
