Use artwork that behaves like a silhouette
Bold logos, icons, badges, and closed shapes make better reliefs than illustrations that depend on gradients, blur filters, hairline strokes, or subtle transparency.
Sanitize untrusted SVG before rendering
SVG can contain active or external content. OpenFileTools removes unsafe/external behavior before rendering the visual result into a local mask.
Understand the rasterization tradeoff
The workflow preserves the rendered SVG aspect ratio, crops to detected artwork, adds controlled plate padding, and converts the result into a bounded high-detail mask. It remains a relief generator rather than a vector CAD solid, so curves are not mathematically parametric after conversion.
Check minimum printable features
Thin gaps or strokes can disappear after thresholding or in the printer itself. Preview the STL at intended physical size and inspect the slicer path before printing.
