SVG to STL converter

To convert an SVG to an STL, give its flat shapes a height: drop the SVG above, set the width and the height in millimetres, and download a watertight STL. Each fill colour can become its own part, and the 3MF download keeps those parts separate for multicolour printing. Everything runs in your browser.

What carries over from your SVG

The converter reads the SVG's geometry, draws each colour in paint order at high resolution, then traces it back into outlines with sub-pixel accuracy. That is what makes overlapping shapes, strokes and even-odd holes come out right.

If the SVG sets its width in millimetres, centimetres or inches, the tool starts at that real size. Otherwise it starts at 80 mm wide, and you type the size you want.

Stroke or fill?

Many icons are drawn as strokes: a line with a width and no fill. A slicer cannot print a line with no area, so the converter turns each stroke into the solid shape it covers on screen. A 2 px stroke on a 24 px icon scaled to 40 mm becomes a line about 3.3 mm wide. Hairline strokes become hairline walls, which is why every part is checked against 0.8 mm, two line widths of a 0.4 mm nozzle, and flagged with the width it measured.

Multicolour prints with a 3MF

With One part per colour on, each fill colour is its own object. Give each colour its own height for a stepped look, or keep them equal for a flat badge you print in one go with an AMS or a tool changer. The 3MF carries one object per colour with its colour attached, and the STL per part download gives you a zip with one file per colour.

If you print with one extruder, set different heights per colour and swap filament at each height. The filament swap height guide shows how to place those changes.

Base plates, engraving and keychains

• Rectangle: a plate around the art. Margin is the space to the edge; a corner radius of 0 gives square corners.
• Outline: a plate that follows the artwork at the distance you set, like a sticker border.
• Engrave into the base: the art is sunk into the plate. The 3MF adds an inlay part for each colour that fills the engraving flush with the top.
• Keychain tab: a tab with a hole on the left, top or right, with the hole diameter and position in millimetres.
• Mirror: flips the model so a stamp reads the right way round when pressed.

Every part is built as its own closed shell and checked for open edges before you download, so slicers accept it without repair. You can confirm the size and shape in the STL viewer.

Other ways to convert SVG to STL

• Tinkercad: in the 3D workspace, press Import and select the SVG. The Tinkercad help center says it becomes a solid shape with a default height that you can scale, and that curves are converted to a best approximation of straight lines.
• Bambu Studio: File, Import, then pick the SVG, as the Bambu Lab wiki shows. Bambu Studio added SVG import in version 1.4.
• OrcaSlicer: File, Import accepts SVG and extrudes its shapes, according to the OrcaSlicer wiki.
• PrusaSlicer 2.7 and later: right-click an object, then Add part, SVG, per the Prusa knowledge base.
• Autodesk Fusion: in the Design workspace, Insert, Insert SVG, pick a face, then Solid, Create, Extrude.
• Blender: File, Import, SVG as Curves (Scalable Vector Graphics in Blender 4.x), give the curves depth with Extrude in the Geometry panel, then Object, Convert, Mesh and export the STL. The Blender manual notes that the importer reads path geometry only and ignores fills, strokes and text.
