Perimeters to wall thickness

Estimate a fixed-width wall with rounded, overlapping extrusion lines.

When this helps

Estimate a fixed-width wall with rounded, overlapping extrusion lines. Start with Extrusion width; this calculator reports Estimated wall thickness.

Method

Line spacing = width − height × (1 − π ÷ 4). Wall = width + (perimeters − 1) × spacing. Also shows perimeters × width.

Worked example

Example inputs

Extrusion width
0.45 mm
Layer height
0.2 mm
Perimeter count
3 count

Calculated outputs

Estimated wall thickness
1.264159 mm
Thickness without bead overlap
1.35 mm

How to read the result

With these example inputs, Estimated wall thickness is 1.264159 mm. Use that value for the setting or decision named above, and read the other outputs as supporting checks.

Common mistake

Do not leave Extrusion width at the example value of 0.45 mm unless it matches your own measurement.

Assumptions and limits

A classic fixed-width estimate, not Arachne or variable-width output. Overlap settings, first layers and geometry can change the wall.
