Rendered from this exact STL file, not from a second source. Single material — the STL format carries no colour channel. Colours in the preview are assigned by the renderer from the element palette and are not part of the downloadable geometry.

The element symbol is cut into the sphere, not printed on it. That single difference is what this variant is for.

• Print it and you can still read it. The letters are part of the solid, so they survive 3D printing. Pick up the printed model and every atom tells you what it is — no legend, no colour key, no separate sheet. A painted label would vanish the moment the file leaves the screen.
• It cannot lose its labelling. The symbol is geometry, not a texture or a material. Open the file in any viewer, any slicer, any CAD package — on any machine, in any colour scheme — and the letters are still there, because there is nothing to strip away.
• Bond order is visible in the shape itself. Single, double and triple bonds are built as one, two and three cylinders, following the PubChem Kekulé structure, so a double bond looks like a double bond in your hand. An aromatic ring therefore appears as one Kekulé structure (alternating single and double bonds), although in the real molecule its ring bonds are delocalised, intermediate between single and double.
• Teaching and display models that stay correct. Nothing about the identification depends on the software, the render settings or the filament colour.

Why the preview looks the way it does. A carved letter has no colour of its own — on a pale atom it would disappear into the highlight. The preview is rendered from the mesh itself with ray-traced cavity shading, so recesses darken because they are recessed, not because we painted them. What you see is the geometry you will receive. The element colours follow the same palette as the interactive viewer on this site, so the model and the viewer never disagree about what an atom is.

Element symbols are recessed into the atom spheres. Mesh: 338,396 triangles versus 10,752.

Validation: mesh validity check PASS before publication (2026-10-14); external cross-check NOT PERFORMED for this model
Recommended print scale: FDM (0.4 mm nozzle, 0.2 mm layer) at least 7.2 mm per Å (model about 60 mm across); resin printer (50 µm) at least 1.7 mm per Å (about 15 mm). Below this scale the engraved symbols become too fine to print. The printer limits are typical values assumed by MolGod, not a test of your printer.
