Calculate Extrusion Multiplier





Formula

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

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

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:

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:

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.
