Detail and lettering

Minimum sizes for raised and engraved detail and for text, by finish.

Use this when: a model has text, logos, engraving or fine surface detail.

Don't use this for: thin parts that stick out from the body. Read Protrusions and loops.

Fine detail must survive finishing. Glossy coating rounds edges and fills shallow engraving, so glossy limits are larger. For lettering, stroke width matters more than font size (DET-05).

Diagram: a part in cross-section with a raised line on the left, its height and width marked, and an engraved groove on the right, its depth and width marked.

Raised detail needs height (0.2 mm matte, 0.3 mm glossy, DET-01) and line width (0.5 mm matte, 0.6 mm glossy, DET-04). Engraved detail needs depth (0.4 mm matte, 0.5 mm glossy, DET-02) and line width (0.4 mm matte, 0.5 mm glossy, DET-03).

Detail	Matte	Glossy	Clear	Rule
Raised detail height	0.2 mm	0.3 mm	0.3 mm	`DET-01`
Engraved depth	0.4 mm	0.5 mm	0.5 mm	`DET-02`
Engraved line width	0.4 mm	0.5 mm	0.5 mm	`DET-03`
Raised line width	0.5 mm	0.6 mm	0.6 mm	`DET-04`
Raised letter stroke width	0.6 mm	0.8 mm	0.8 mm	`DET-05`
Raised letter height	0.4 mm	0.5 mm	0.5 mm	`DET-06`
Character height	3 mm	4 mm	4 mm	`DET-07`
Free-standing letter thickness	2 mm	2.5 mm	2.5 mm	`DET-08`

Use instead

Wrong move: a thin serif font for raised text. Why: hairline strokes break or fill in. Right move: a bold sans with strokes of at least 0.6 mm matte, 0.8 mm glossy (DET-05).
Wrong move: shallow engraving on a glossy part. Why: coating fills it. Right move: engrave at least 0.5 mm deep on glossy (DET-02), or choose matte.
