How do I turn my logo into an STL file?

Trace the logo's outlines into vector paths and extrude them into a solid. You can do it manually (vectorize to SVG, then extrude in Tinkercad or CAD) or in one step with an online tool that traces and extrudes together and returns an STL plus 3MF.

Why did parts of my logo print as separate loose pieces?

The enclosed centers of letters like O, A, and D are separate shapes with nothing holding them once the surrounding material is gone. Put a baseplate about 2 mm thick under the whole design and group everything into one solid before exporting.

How thick should a 3D printed logo be?

A 2 mm base with the logo raised 3 to 5 mm above it is a reliable recipe. It is rigid, prints quickly, and the height difference leaves room for a clean filament color change at the logo layer.

Can I print a two-color logo without a multi-material printer?

Yes. Add a filament change in your slicer at the layer where the raised logo begins. The base prints in the first color, the printer pauses, you swap spools, and the logo prints in the second color. One nozzle, two crisp colors.

What logo files work best for 3D printing?

Bold, high-contrast versions with clean edges. A flat single-color logo on a plain background converts almost perfectly. Gradients, drop shadows, and photographic textures do not survive the trip to solid geometry, so use the simplest official version of the mark.

How to 3D Print a Logo from a PNG or JPG

A 3D printed logo is one of those projects that looks like it should be trivial and then eats an afternoon. The image is right there. The printer is right there. But between them sits a format gap: your logo is flat pixels and a printer needs solid geometry, and the standard advice routes you through two or three tools to cross it. Here is the whole path, the one-step shortcut, and the two numbers (2 mm and 5 mm) that separate a crisp desk plaque from a pile of loose letter centers.

What makes a logo printable

Printability is decided before any conversion happens, by the image you start from:

Bold beats thin. Strokes and details thinner than about a millimetre at print size become fragile spears or vanish entirely. If the logo has a heavyweight variant, use it.
Flat beats fancy. Gradients, glows, and drop shadows cannot become geometry. Grab the flat one-color version of the mark, the one your sign maker would ask for.
Contrast is everything. The conversion traces the boundary between dark and light. A crisp dark logo on a plain light background traces almost perfectly; a logo photographed on a busy background does not.

The same source-image rules from best image size for a 3D printed bookmark apply here, since the pipeline is identical.

The conversion: two routes to solid geometry

The one-step route. ButterySpace's image to 3D tool takes the PNG, JPG, or WebP directly, traces the outlines, extrudes them, and attaches everything to a base in a single pass. You download a 3MF project plus a matched single-body STL, already slicer-ready, already one connected solid. It runs in the browser with no watermark on your mark, and free means free: five free pats of butter a day, a 3D conversion uses two, refilled daily with no sign-up.

The classic route. Vectorize the image to SVG first (the image to SVG converter does this in the browser, or Inkscape's Trace Bitmap if you prefer desktop), then extrude the SVG in Tinkercad: import, set the height, add a base box, group, export STL. The full walkthrough with settings lives in how to convert SVG to STL. Take this route when you want manual control over the shape between the trace and the extrude.

The alphabet soup problem

This is the failure that ruins most first attempts, so it gets its own section. Look at the letter O. Its center is an island: once the ring around it is solid plastic, nothing connects the middle to anything. Same for A, D, R, and the negative space in most logomarks. Extrude the logo alone and those islands print as separate confetti scattered across your bed.

The fix is a baseplate: a slab about 2 mm thick under the entire design, slightly larger than the artwork, grouped with it into one solid. Every island now stands on shared ground. One-step converters that attach a base automatically take this failure off the table entirely, which is exactly why they exist.

The numbers that work

Dimension	Start at	Why
Baseplate thickness	2 mm	Rigid, quick, and holds every island in the design
Logo height above base	3 to 5 mm	Reads clearly in raking light and leaves a clean layer for a color swap
Overall width	80 to 120 mm	Desk-plaque scale; small details survive, print stays under a couple of hours
Layer height	0.2 mm	Fine enough for crisp edges, fast enough to finish before the coffee does

Orientation is simple: flat on the bed, base down, no supports. The printer draws the logo's outline every layer, so the silhouette comes out as sharp as the trace.

Two colors with one nozzle

A solid-color logo looks fine. A logo in brand colors on a contrasting base looks shop-made, and you do not need a multi-material printer to get it. Because the logo starts at a known height (the top of that 2 mm base), you can add a filament change in your slicer at that exact layer: base prints in color one, the machine pauses, you swap spools, the raised logo prints in color two. Bambu Studio users have a second option, painting colors directly onto the model, and both are walked through in how to add color in Bambu Studio.

The finishing pass

Fresh off the extrude, every rim on the part is a dead-sharp 90 degrees. For a piece that gets handled, run the STL through the Round STL tool before slicing: a 0.4 or 0.8 mm fillet along the rims takes the machined edge off and leaves the logo, well, butter to the touch. The embossed detail itself stays crisp; only the edges soften.

The short of it: start from the boldest, flattest version of the logo. Convert in one step or via SVG and Tinkercad. Put everything on a grouped 2 mm baseplate so the letter centers survive, raise the logo 3 to 5 mm, slice it flat with no supports, and swap filament at the logo layer for a two-color finish.
