Transparent Coating

Transparent Coating adds a separate Coating object outside the display face. It is not automatically assigned a real transparent filament; map the object to the transparent material you intend to print in your slicer.

Coating height

The interface offers 0.04, 0.08, and 0.12 mm, with 0.08 mm as the default. The generator cannot create a fractional layer: it divides coating height by the active model layer height, rounds the result, and keeps at least one layer. Effective thickness is therefore complete layers × model layer height; the UI value is a request, not a guarantee that the slicer will receive that exact physical thickness.

For example, with a 0.08 mm model layer height, a 0.04 mm request still becomes one 0.08 mm layer, while a 0.12 mm request becomes two layers, or 0.16 mm. Use an exact multiple of the active layer height when physical thickness matters.

Coating follows the model silhouette. When Outline is enabled, coverage expands over the outline edge as well.

Why the coating may disappear after slicing

Coating is generated outside the model's bottom face and can initially sit below the build plate. The slicer may show the object in its list while omitting the below-bed geometry.

Select the complete model, use Place on Bed or Auto Arrange, then slice again. Verify that the first layer contains the transparent-material path.

Transparent PETG is a common option, not a required brand or material. Test material compatibility and temperatures on a small sample first.
