3D Printing Quality (Small-Scale) Calculator Examples
Explore worked small-scale FDM printing examples using different nozzles, layer heights, line widths, feature sizes, and model heights.
These examples show how nozzle size, layer height, line width, and minimum feature size change the calculator's detail score. They are planning examples for comparing settings before making a test print.
Miniature at balanced 0.12 mm layers
A hobby model has 0.5 mm raised trim and small surface details that need to remain visible.

The settings produce an estimated quality score of 88%, a 0.10 mm recommended layer height, and 250 layers.
Fine 0.25 mm nozzle for narrow details
A 20 mm model has narrow decorative ridges that would be difficult to represent with a 0.4 mm line width.

How to Read Your Results
Use the recommended layer height as a fine-detail starting point based on the entered nozzle, not as a mandatory setting.
A higher estimated layer count means finer vertical increments but usually a longer print.
A feature-to-line ratio of 1 or more means the smallest feature is at least one selected line width wide.
A ratio below 1 indicates that the feature is narrower than the selected line width and may be simplified, merged, or omitted.
Compare the vertical and horizontal conditions separately rather than relying only on the combined score.
Assumptions & Important Notes
- Each example uses the calculator's 25%-of-nozzle-diameter fine-detail layer-height target.
- The examples assume FDM or FFF printing with a round nozzle.
- No adaptive layers, variable line widths, or special thin-wall behavior are included in the arithmetic.
- Scores describe selected geometry and settings rather than a guaranteed finished-print result.

Frequently Asked Questions
Which example is best for miniature details?
The 0.25 mm nozzle example is best suited to the narrowest modeled features because it uses a 0.28 mm line width and a 0.06 mm layer height.
Why does the coarse-layer example still have a 100% horizontal score?
Its 0.8 mm smallest feature is wider than its 0.45 mm line width. Horizontal score only evaluates feature width, not layer height.
Can a 0.4 mm nozzle print a 0.25 mm feature?
The example gives it a 0.63× feature-to-line ratio, indicating that it is narrower than the selected 0.4 mm line width. Actual slicer output may alter or omit it.
Why can a print have a high total score with a narrow feature?
The formula weights vertical detail at 60%. A perfect vertical score can partly offset a lower horizontal score, so reviewing the ratio remains important.
