3MF · recommended
Records millimeters explicitly and packages the checked triangle mesh in a modern manufacturing format.

Terrain to a physical object
Turn a real place into a topographic map you can actually print.
Choose the exact area first. We build the terrain surface, side walls and flat base, then check topology, orientation, physical dimensions and minimum base thickness before a download is allowed.

A pass means measurable geometry—not a hopeful STL button.
This Zhangjiajie terrain was generated in the live editor at 160 mm width. The repaired result was independently re-read from both 3MF and STL during validation.

Zhangjiajie · 160 mm verified sample
160.0 × 140.7 × 20.7 mm, with a 4.13 mm minimum base. Use it to test your slicer before creating your own place.
3MF
Recommended. Stores millimeters in the file.
STL
Legacy compatibility. Confirm millimeters in your slicer.
From map to slicer
Four steps, with the risky part checked before sign-in.
- 01
Frame the terrain
Search a mountain, city or coordinate and resize the centered frame around only the area you want.
- 02
Shape the relief
Generate the real terrain, then adjust elevation and base depth in the 3D editor.
- 03
Inspect and repair
Open the print check for dimensions, open edges, non-manifold edges, solid count and base thickness. This is free.
- 04
Slice, then print
Download 3MF or STL after the model passes. Confirm orientation, supports, layer height, nozzle and material in your slicer.
Choose the handoff
Use 3MF by default. Keep STL for older workflows.
STL · compatible
Carries the same repaired geometry at millimeter scale, but STL itself has no reliable unit field. Confirm mm on import.
Honest manufacturing boundary
Only geometry we can check is included.

Those elements remain visible in the scene, but they are not silently added to the print file until they can be unioned and checked independently.
3D printable topographic map questions
How do I turn terrain into an STL file?+
Search a place, frame the exact area, generate the terrain and choose Prepare a printable terrain in the Export panel. When the model is one watertight solid with a safe base, you can download STL or the recommended 3MF file.
Is this a Google Earth to STL converter?+
No. Make3DMap does not extract imagery or 3D meshes from Google Earth. You select coordinates in our map interface and the product builds a terrain model from its supplied elevation workflow and attributed map sources.
Is the model guaranteed to print on every 3D printer?+
No. The check covers mesh topology, orientation, physical dimensions and baseline base thickness. Your slicer and printer settings still determine supports, layer height, nozzle, material and final manufacturability.
Why is 3MF recommended over STL?+
3MF stores millimeters explicitly. STL only stores triangle coordinates, so the same file can import at the wrong scale unless you confirm millimeters in the slicer.
Can buildings, labels or trails be printed too?+
Not in the checked terrain export yet. They require boolean union, wall-thickness and self-intersection checks of their own. Excluding them is safer than presenting an unchecked scene as print-ready.
Do I need an account to check my terrain?+
No. You can select a place, generate the terrain and see the full print inspection first. Sign-in is requested only when you download a passing 3MF or STL file.
Start with the place you want to hold.
The selector is at the top of this page. Frame the exact terrain and generate it; the editor opens on Export, where you can start the print check when ready.
