STL export
Export a map as STL or 3MF for 3D printing
This workflow is designed for people who need an actual printable file, not only a screen preview. Use it to generate STL and 3MF map models with configurable roads, building massing, terrain and highlight markers.
Why STL output matters
If a map is meant for fabrication, the important part is the geometry. You need a file that holds up in a slicer, reads clearly at your chosen size and can be adjusted before printing. CreateYourMap.com focuses on that export step by letting you tune height, width and visibility for the main visual layers before download.
STL is the most universal route into desktop 3D printing. 3MF is often better when you want richer workflow data or a more modern handoff. Supporting both formats makes the project practical for hobby printers, agencies and studios that pass models between multiple tools.
Good export habits
- Keep the area focused so streets and buildings stay legible at the final print size.
- Use flatter terrain for dense cities and stronger elevation only where landform matters.
- Turn off unnecessary layers when the composition starts to look crowded.
- Use markers to tell a story instead of trying to label everything in the model itself.
STL map generator use cases
Personal gift maps
Create a model around a hometown, proposal spot, wedding venue or favorite travel destination.
Studio prototypes
Generate context models for early massing studies, presentations or informal site discussions.
Educational terrain pieces
Export landform-heavy regions where the relief is part of the story.
Wall display projects
Switch to poster-style output when you want a cleaner graphical interpretation rather than a thicker 3D object.

Best starting slicer settings for STL maps
Layer height: 0.20 mm
Use this as the baseline for most prints. Drop to 0.16 mm when the design is small and fine detail matters.
Walls: 3 perimeters
Three walls are a good default for preserving thin roads and sharper building outlines.
Top and bottom layers
Use 4 bottom layers and 4 to 5 top layers so the base and upper surfaces stay solid.
Infill: 12 to 18 percent
This is usually enough for a strong map body without overbuilding the part.
Supports: off by default
Map prints should usually sit flat on the build plate and avoid support-heavy geometry.
Outer wall speed: slightly reduced
If the print looks soft around roads or building edges, slow the outer walls before changing everything else.
Frequently asked questions
Which is better for map printing: STL or 3MF?
STL is the safest universal choice because almost every slicer supports it well. 3MF is often the better modern format when you want a richer workflow, but if compatibility is the priority, STL remains the default.
What slicer profile should I start with for an STL map?
A practical starting point is a 0.20 mm layer height, 3 walls, 4 to 5 top layers, 4 bottom layers and 12 to 18 percent infill. If the model contains very fine roads or small marker details, lower the layer height slightly and slow outer walls.
Do map models need supports?
Usually not. A well-prepared map STL should print flat on its base without supports. If you see major unsupported bridges or suspended decorative details, the model or settings should usually be simplified instead of relying on support material.
How do I get cleaner building and road detail?
Use a smaller geographic crop, keep the print size realistic for the amount of detail, and reduce visual clutter by disabling layers that do not help the composition. Fine detail prints better when the model is simplified before export.
