Working…

1 · Select a region

Draw any rectangle, or drop a preset square at the current map center. Up to 4 km across includes real buildings; up to 50 km for terrain-only mountain & landscape models.

2 · Model settings

Model size (longest side) 180 mm

Base 4 mm

Vertical scale 1.0×

1.0× keeps elevation and buildings at the exact same scale as the ground — a true 1:1 scale model. Raise it to exaggerate subtle terrain.

Include real buildings (OpenStreetMap)

Default building height 8 m

Used when OpenStreetMap has no height or floor count recorded for a building.

Water & parks — carve rivers/lakes, raise parks

Pulls rivers, lakes, ponds and green spaces from OpenStreetMap. Water is leveled and sunk into a recessed basin so rivers and ponds read as real channels with banks, and parks are raised onto a low pad — both are printable 3D features baked into the STL. The preview tints water blue and parks green; the colors themselves are preview-only (a plain STL has no color).

Select a region on the map first.

3 · Print-ready checks

Model size— Print scale— Triangles— Buildings— Elevation range—

The combined STL is watertight per shell and slices correctly in Bambu Studio, OrcaSlicer, PrusaSlicer, and Cura. Separate STLs let you print buildings in a second color.

Your generated model, geometry checks, and STL download will appear here.

1:1 Scale Map Generator — Turn Real-World Terrain & Buildings into 3D Printable Models

This 1:1 map generator builds true-to-scale, 3D printable models of any place on Earth straight from real geographic data. Pan and search the live map, draw the region you want, and export a watertight STL of the actual terrain elevation and building footprints — no GIS software, no DEM downloads, and no mesh cleanup in Blender. Everything runs in your browser using open, commercially-licensed data. Generating and downloading models is included with a PrintPal subscription.

Looking for stylized, artistic city maps instead?

Try the AI 3D Map Maker — it generates charming diorama-style city and landscape models from a text prompt, perfect for souvenirs and gifts when you don't need exact 1:1 scale accuracy.

Open AI Map Maker

Accurate 3D Maps from Real OpenStreetMap & Elevation Data

Unlike AI-generated map tools that create stylized miniatures, this generator uses authentic geospatial data to produce dimensionally accurate models. Terrain comes from global elevation tiles, building heights and footprints come from OpenStreetMap, and water bodies and parks are detected and rendered cleanly. The result is a real, measurable scale model of your chosen region — ideal when proportions and placement actually matter.

How the 1:1 Map Generator Works

Find your location — Search any city, address, neighborhood, mountain, or landmark, or simply pan and zoom the interactive map.
Set your region — Choose the area you want to capture. The tool fetches terrain elevation and building data for exactly that bounding box.
Tune the output — Adjust physical model size, base thickness, vertical scale, and toggle buildings, water, and parks.
Generate & check — Terrain and buildings are meshed, rivers and lakes are carved into recessed water basins, parks are raised onto a pad, and the geometry runs through automatic print-readiness checks (vertex welding, degenerate-triangle removal, watertight shells).
Download STL — Export a single combined STL or terrain and buildings as separate STLs for multi-color printing.

What You Can Make

Scale models of your city or neighborhood — Real buildings and streets at accurate relative proportions.
Topographic & relief maps — True elevation models of mountains, valleys, coastlines, and trails.
Architecture & urban planning context models — Drop a real site into a presentation or massing study.
Hiking, ski, and national park terrain — Print the real landscape of a route or region.
Personalized keepsakes — A 3D print of a hometown, a favorite trip, or a meaningful place — at real scale.
Education & museum pieces — Tangible geography and earth-science models built from real data.

Print-Ready Geometry, Every Time

The exported STL is designed to slice cleanly in Bambu Studio, OrcaSlicer, PrusaSlicer, and Cura. Each shell is watertight, rivers and lakes are carved into recessed water basins, parks are raised onto a low pad, and buildings sit correctly on the terrain. You can export the model as a single solid or split terrain and buildings into separate STLs so you can print them in different colors or materials.

1:1 Map Generator vs. AI Map Maker

Use this 1:1 Scale Map Generator when you want geographic accuracy — real elevation, real building footprints, and a model that's true to scale. Use the AI 3D Map Maker when you want a beautiful, stylized diorama or miniature generated from a text description, where artistic appeal matters more than exact measurements. Many makers use both: this tool for accurate terrain and the AI tool for decorative city scenes.

Frequently Asked Questions

Is it really 1:1 scale? The model is built at the real relative proportions of the region you select, then scaled down to the physical print size you choose. Distances, building placement, and terrain are accurate to the source data; vertical scale can be exaggerated optionally for dramatic relief.

Do I need to download elevation data or use GIS software? No. Everything — search, terrain, buildings, meshing, geometry checks, and STL export — happens in your browser.

What does it cost? Browsing the map is free, and generating or downloading 1:1 scale models is included with an active PrintPal subscription. The generation itself still runs entirely in your browser using open data — there are no per-export credits. See pricing for current plans.

Where does the building data come from? OpenStreetMap footprints and height tags. Coverage is excellent in cities and varies in rural areas; buildings without height data use a sensible default.

Can I print it in multiple colors? Yes. Export terrain and buildings as separate STLs and assign different colors or materials in your slicer.

Is this better than Terrain2STL, TouchTerrain, or Cadmapper? For a quick, browser-based way to get both terrain and buildings as a print-ready STL with automatic geometry checks, yes. For specialized survey-grade GIS exports, a dedicated GIS pipeline may still be preferable.
