3D print your logo from an SVG or PNG

Published 2026-10-25

A printed logo makes a good keychain, badge, desk sign, fridge magnet or event giveaway, and it's one of the easiest things to print well. Here's how to go from a logo file to a good print.

1. Make the STL

Open the SVG to STL page, add your logo and set:

• Depth: the STL is 60 mm along its longest side, and the depth slider runs from about 2 to 17 mm at that size. After scaling, aim for 3 to 5 mm for keychains and badges, and 6 to 10 mm for a free-standing sign.
• Bevel: zero for crisp, flat-topped prints; a little for a rounded, moulded look. Bevels print best with fine layers.

Then download the STL.

2. Scale it in your slicer

Open the STL in your slicer (PrusaSlicer, Cura, Bambu Studio and others) and scale it to the size you want; the proportions stay locked. Check the thinnest parts: on most FDM printers, walls under about 0.8 mm (two line widths with a 0.4 mm nozzle) print badly or not at all. If details vanish, print larger or thicken them in the original artwork.

3. Print settings that suit logos

• Lay it flat. No supports needed.
• Layer height: 0.12 to 0.2 mm. Finer layers show bevels better.
• Top layers: five or more for a smooth top face. Ironing, if your slicer has it, gives a glossy top.
• First layer: slow and well levelled, since this is the face people see if you print it face-down.

4. Two colours with one nozzle

Logos look great in two colours, and you don't need a multi-material printer:

1. Print a base plate (or a backing in your slicer) with the logo on top.
2. Add a filament change ("pause at height", or M600) at the layer where the logo starts.
3. When the printer pauses, swap to the second colour.

5. Keyrings and magnets

• Keyring hole: add a small cylinder in your slicer as a negative volume, or add a loop in your artwork before tracing.
• Magnets: pause at a layer to drop in a magnet, or glue one into a recess afterwards.
